Vulnerability Details

Babel is a compiler for writingJavaScript. In "@babel/traverse" prior to versions 7.23.2 and 8.0.0-alpha.4 and all versions of "babel-traverse", 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; and 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. The vulnerability has been fixed in "@babel/traverse@7.23.2" and "@babel/traverse@8.0.0-alpha.4". Those who cannot upgrade "@babel/traverse" and are using one of the affected packages mentioned above should 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.

Vulnerability Details

Impact:
The fix for CVE-2021-23337 (GHSA-35jh-r3h4-6jhm) added validation for the variable option in _.template but did not apply the same validation to options.imports key names. Both paths flow into the same Function() constructor sink.
When an application passes untrusted input as options.imports key names, an attacker can inject default-parameter expressions that execute arbitrary code at template compilation time.
Additionally, _.template uses assignInWith to merge imports, which enumerates inherited properties via for..in. If Object.prototype has been polluted by any other vector, the polluted keys are copied into the imports object and passed to Function().
Patches:
Users should upgrade to version 4.18.0.
Workarounds:
Do not pass untrusted input as key names in options.imports. Only use developer-controlled, static key names.

CVE-2026-33671

Blazing fast and accurate glob matcher written in JavaScript, with no dependencies and full support for standard and extended Bash glob features, including braces, extglobs, POSIX brackets, and regular expressions.

Found in HEAD commit: 38f0b2a12b49cb8bb351c740ae839aa41590ad3a

Found in base branch: main

Vulnerability Details

Picomatch is a glob matcher written JavaScript. Versions prior to 4.0.4, 3.0.2, and 2.3.2 are vulnerable to Regular Expression Denial of Service (ReDoS) when processing crafted extglob patterns. Certain patterns using extglob quantifiers such as "+()" and "()", especially when combined with overlapping alternatives or nested extglobs, are compiled into regular expressions that can exhibit catastrophic backtracking on non-matching input. Applications are impacted when they allow untrusted users to supply glob patterns that are passed to "picomatch" for compilation or matching. In those cases, an attacker can cause excessive CPU consumption and block the Node.js event loop, resulting in a denial of service. Applications that only use trusted, developer-controlled glob patterns are much less likely to be exposed in a security-relevant way. This issue is fixed in picomatch 4.0.4, 3.0.2 and 2.3.2. Users should upgrade to one of these versions or later, depending on their supported release line. If upgrading is not immediately possible, avoid passing untrusted glob patterns to "picomatch". Possible mitigations include disabling extglob support for untrusted patterns by using "noextglob: true", rejecting or sanitizing patterns containing nested extglobs or extglob quantifiers such as "+()" and "()", enforcing strict allowlists for accepted pattern syntax, running matching in an isolated worker or separate process with time and resource limits, and applying application-level request throttling and input validation for any endpoint that accepts glob patterns.

Vulnerability Details

Lodash versions 4.0.0 through 4.17.22 are vulnerable to prototype pollution in the _.unset and _.omit functions. An attacker can pass crafted paths which cause Lodash to delete methods from global prototypes.
The issue permits deletion of properties but does not allow overwriting their original behavior.
This issue is patched on 4.17.23

Vulnerability Details

Impact:
Lodash versions 4.17.23 and earlier are vulnerable to prototype pollution in the _.unset and _.omit functions. The fix for (CVE-2025-13465: GHSA-xxjr-mmjv-4gpg) only guards against string key members, so an attacker can bypass the check by passing array-wrapped path segments. This allows deletion of properties from built-in prototypes such as Object.prototype, Number.prototype, and String.prototype.
The issue permits deletion of prototype properties but does not allow overwriting their original behavior.
Patches:
This issue is patched in 4.18.0.
Workarounds:
None. Upgrade to the patched version.

Vulnerability Details

Picomatch is a glob matcher written JavaScript. Versions prior to 4.0.4, 3.0.2, and 2.3.2 are vulnerable to a method injection vulnerability affecting the "POSIX_REGEX_SOURCE" object. Because the object inherits from "Object.prototype", specially crafted POSIX bracket expressions (e.g., "[[:constructor:]]") can reference inherited method names. These methods are implicitly converted to strings and injected into the generated regular expression. This leads to incorrect glob matching behavior (integrity impact), where patterns may match unintended filenames. The issue does not enable remote code execution, but it can cause security-relevant logic errors in applications that rely on glob matching for filtering, validation, or access control. All users of affected "picomatch" versions that process untrusted or user-controlled glob patterns are potentially impacted. This issue is fixed in picomatch 4.0.4, 3.0.2 and 2.3.2. Users should upgrade to one of these versions or later, depending on their supported release line. If upgrading is not immediately possible, avoid passing untrusted glob patterns to picomatch. Possible mitigations include sanitizing or rejecting untrusted glob patterns, especially those containing POSIX character classes like "[[:...:]]"; avoiding the use of POSIX bracket expressions if user input is involved; and manually patching the library by modifying "POSIX_REGEX_SOURCE" to use a null prototype.
