CVE-2023-45133

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/[email protected] and
@babel/[email protected]. 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.
