Security Advisories 🚨

🚨 Babel has inefficient RegExp complexity in generated code with .replace when transpiling named capturing groups

Impact

When using Babel to compile regular expression named capturing groups, Babel will generate a polyfill for the .replace method that has quadratic complexity on some specific replacement pattern strings (i.e. the second argument passed to .replace).

Your generated code is vulnerable if all the following conditions are true:

  • You use Babel to compile regular expression named capturing groups
  • You use the .replace method on a regular expression that contains named capturing groups
  • Your code uses untrusted strings as the second argument of .replace

If you are using @babel/preset-env with the targets option, the transform that injects the vulnerable code is automatically enabled if:

  • you use duplicated named capturing groups, and target any browser older than Chrome/Edge 126, Opera 112, Firefox 129, Safari 17.4, or Node.js 23
  • you use any named capturing groups, and target any browser older than Chrome 64, Opera 71, Edge 79, Firefox 78, Safari 11.1, or Node.js 10

You can verify what transforms @babel/preset-env is using by enabling the debug option.

Patches

This problem has been fixed in @babel/helpers and @babel/runtime 7.26.10 and 8.0.0-alpha.17, please upgrade. It's likely that you do not directly depend on @babel/helpers, and instead you depend on @babel/core (which itself depends on @babel/helpers). Upgrading to @babel/core 7.26.10 is not required, but it guarantees that you are on a new enough @babel/helpers version.

Please note that just updating your Babel dependencies is not enough: you will also need to re-compile your code.

Workarounds

If you are passing user-provided strings as the second argument of .replace on regular expressions that contain named capturing groups, validate the input and make sure it does not contain the substring $< if it's then not followed by > (possibly with other characters in between).

References

This vulnerability was reported and fixed in #17173.

Security Advisories 🚨

🚨 Babel vulnerable to arbitrary code execution when compiling specifically crafted malicious code

Impact

Using Babel to compile code that was specifically crafted by an attacker can lead to arbitrary code execution during compilation, when using plugins that rely on the path.evaluate()or path.evaluateTruthy() internal Babel methods.

Known affected plugins are:

  • @babel/plugin-transform-runtime
  • @babel/preset-env when using its useBuiltIns option
  • Any "polyfill provider" plugin that depends on @babel/helper-define-polyfill-provider, such as babel-plugin-polyfill-corejs3, babel-plugin-polyfill-corejs2, babel-plugin-polyfill-es-shims, babel-plugin-polyfill-regenerator

No other plugins under the @babel/ namespace are impacted, but third-party plugins might be.

Users that only compile trusted code are not impacted.

Patches

The vulnerability has been fixed in @babel/traverse@7.23.2.

Babel 6 does not receive security fixes anymore (see Babel's security policy), hence there is no patch planned for babel-traverse@6.

Workarounds

  • Upgrade @babel/traverse to v7.23.2 or higher. You can do this by deleting it from your package manager's lockfile and re-installing the dependencies. @babel/core >=7.23.2 will automatically pull in a non-vulnerable version.
  • If you cannot upgrade @babel/traverse and are using one of the affected packages mentioned above, upgrade them to their latest version to avoid triggering the vulnerable code path in affected @babel/traverse versions:
    • @babel/plugin-transform-runtime v7.23.2
    • @babel/preset-env v7.23.2
    • @babel/helper-define-polyfill-provider v0.4.3
    • babel-plugin-polyfill-corejs2 v0.4.6
    • babel-plugin-polyfill-corejs3 v0.8.5
    • babel-plugin-polyfill-es-shims v0.10.0
    • babel-plugin-polyfill-regenerator v0.5.3

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Full Changelog: https://github.com/jestjs/jest/blob/main/CHANGELOG.md

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

Release Notes

0.25.24 (from changelog)

Updates:

  • 331 Implements an additional check specific to property types of required & undefined. This to ensure the property key exists when the property value extends undefined.
  • 331 Documentation updates for Ajv and TypeCompiler

Additional:

  • 331 Remove unusued recursive code paths for create and cast.

0.25.23 (from changelog)

Updates:

  • 324 TypeScript Language Service now presents JSDoc comments when inferring static object properties. (IntelliSense)
  • 325 Additional property inference optimizations.

Additional:

  • Huge thank you to Github user stevezhu for these excellent contributions.

0.25.22 (from changelog)

Updates:

  • 323 adds compiler support for UTF-16 (unicode) characters for schema identifiers.

0.25.18 (from changelog)

Updates:

  • 307 implements date conversion when casting values with Value.Cast(Type.Date(), ...). Castable values include numbers (interpretted as timestamps) and iso8601 string values. Uncastable values will result in dates with values of 1970-01-01T00:00:00.000Z. This version also includes more robust checks for Dates initialized with invalid values.

0.25.11 (from changelog)

Updates:

  • 286 implements a FNV1A-64 non cryptographic hashing function in TypeBox. This function should not be used in place of cryptographic hashing functions, rather it's purpose is to provide relatively fast, hashing mechanism to assist with checks for arrays with uniqueItems constraints, specifically for cases where the array may contains reference values (such as objects, arrays, Dates and Uint8Array). This function is provided via Value.Hash() for convenience as the hash may be useful to generate a numeric identifier for values (with some considerations to React array rendering in absence of key or identifier)

0.25.10 (from changelog)

Updates:

  • 283 Updates the custom type validator callback signature to accept a schema instance. The schema instance may include additional constraints (such as options) that may be used during the validation process. Custom.Set('<Kind>', (schema, value) => { ... }).

0.25.9 (from changelog)

Updates:

  • 282 TypeBox now supports custom types. These types require the user to specify a custom [Kind] string on the type. Custom types can be registered via Custom.Set('<Kind>', (value) => { ... }) which allow the TypeCompiler and Value API's to make use of user defined validation logic.

0.25.0 (from changelog)

Updates:

  • 271 Adds a new non-standard Type.Date() type. This type joins the existing Type.UInt8Array() as a promoted extended type used to represent core JavaScript primitives. It's inclusion was prompted by end user requirements to validate Date objects prior to writing them to Date supported API's and where serialization of the Date object is handled internally by the API.

  • 271 Redesign of Extended Type representations. Extended types been updated to provide external validators (such as Ajv) additional standard proporties to use when defining the custom schema. These properties are instanceOf (used for validating a class object instances), and typeOf (when validating value types). Information on configuring Ajv for these properties can be found in the Ajv section of the TypeBox readme.

0.24.49 (from changelog)

Updates:

  • 264 TypeBox now provides preliminary support for non-boolean additionalProperties. This allows existing TObject schemas to be augmented with additional properties of a known type.

Additional:

  • TypeBox provides an additional reference codegen module for generating raw JSON Schema from TypeScript types via the TS compiler API. This generator may be used in future tooling.

0.24.44 (from changelog)

Updates:

  • 189 Both Value.Error(T, value) and TypeCheck.Error(value) now return an iterator for validation errors.
  • 191 TypeBox now provides a TypeGuard API that can be used to check the structural validity of TypeBox type. The TypeGuard can be used in reflection / code generation scenarios to resolve the appropriate inner TSchema type while traversing a outer type.
  • 197 TypeBox now implements conditional runtime type mapping. This functionality is offered as seperate import for the 0.24.0 release but may be provided as standard type in later releases. This API enables type T = Foo extends Bar ? true : false conditional checks to be implemented at runtime. This API also provides the Exclude and Extract utility types which are implemented through conditional types in TypeScript.
  • 199 TypeBox now provides better support for varidiac function and constructor signatures. Currently Variadics are mapped through Tuple types.
  • 200 The types TPick and TOmit now support types of TUnion<TLiteral<string>[]> to be used to select properties. Additionally, KeyOf now returns TUnion<TLiteral<string>[]>, allowing KeyOf schemas to be passed to TPick and TOmit.
  • 214 TypeBox now provides better support for i18n. To achieve this, TypeBox includes fixed mappable error codes on the ValueError type. These codes can be used by external implementors to create localized error messages. TypeBox may include localized error codes as an optional import in future releases.
  • 288 TypeBox now allows users to implement custom string validator formats. These formats are internally shared between the Value and TypeCompiler API's. TypeBox does not currently provide any built in formats, however the standard expected set (email, uuid, uri, etc) may be provided via optional import (inline with ajv-formats usage)
  • 229 The Value.Cast() function now implements automatic coersion of string, number and boolean types.
  • 231 TypeBox provides a new Value.Diff<T>() and Value.Patch<T>() utility API for JavaScript values. This API is intended to provide a basis for the efficient transmission of state updates across a network. This API can diff any JavaScript value (typed or untyped) but is recommended to be used in conjunction with a formal static type.
  • 236 TypeBox now implements the TNever type. This type is analogous to TypeScript's never type and is used in instances a composition results in a non-reconcilable type. Currently this type is implemented for empty TUnion<[]> types only. Future releases may utilize this type for planned updates to TIntersect (for example string & number resolves to never)
  • 241 247 TypeBox now exposes a ValuePointer API that can be used to mutate a value via an RFC6901 JSON Pointer. Previously this functionality was internally used by Value.Diff() and Value.Patch() functions but is now offered as an optional import for implementations that need to update values manually through pointer references.

Additional:

  • This project now includes two reference code generation utilities that can be used in custom build tooling. The first is TypeScriptCodeGen which will remap TypeScript interface and type definitions to TypeBox types. The second is TypeBoxCodeGen which will map existing TypeBox types into TypeScript type definitions. These implementations are not expected to be part of the TypeBox package, but users are free to clone and enhance them in their existing tool chains. Reference implementations can be found https://github.com/sinclairzx81/typebox/tree/master/codegen

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

↗️ braces (indirect, 3.0.2 → 3.0.3) · Repo · Changelog

Security Advisories 🚨

🚨 Uncontrolled resource consumption in braces

The NPM package braces fails to limit the number of characters it can handle, which could lead to Memory Exhaustion. In lib/parse.js, if a malicious user sends "imbalanced braces" as input, the parsing will enter a loop, which will cause the program to start allocating heap memory without freeing it at any moment of the loop. Eventually, the JavaScript heap limit is reached, and the program will crash.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

30.0.0

Today we are happy to announce the release of Jest 30. This release features a substantial number of changes, fixes, and improvements. While it is one of the largest major releases of Jest ever, we admit that three years for a major release is too long. In the future, we are aiming to make more frequent major releases to keep Jest great for the next decade.

If you want to skip all the news and just get going, run npm install jest@^30.0.0 and follow the migration guide: Upgrading from Jest 29 to 30.

↗️ micromatch (indirect, 4.0.5 → 4.0.8) · Repo · Changelog

Security Advisories 🚨

🚨 Regular Expression Denial of Service (ReDoS) in micromatch

The NPM package micromatch prior to version 4.0.8 is vulnerable to Regular Expression Denial of Service (ReDoS). The vulnerability occurs in micromatch.braces() in index.js because the pattern .* will greedily match anything. By passing a malicious payload, the pattern matching will keep backtracking to the input while it doesn't find the closing bracket. As the input size increases, the consumption time will also increase until it causes the application to hang or slow down. There was a merged fix but further testing shows the issue persisted prior to #266. This issue should be mitigated by using a safe pattern that won't start backtracking the regular expression due to greedy matching.
