Name of the Vulnerable Software and Affected Versions @babel/traverse versions prior to 7.23.2 and 8.0.0-alpha.4 babel-traverse (all versions)

Description The issue is related to the path.evaluate() or path.evaluateTruthy() internal Babel methods. 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 these 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. Users that only compile trusted code are not impacted.

Recommendations

• Upgrade @babel/traverse to v7.23.2 or higher.
• 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
