How to fix?

There is no fixed version for babel-traverse.

Overview

Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs when using plugins that rely on the path.evaluate() or path.evaluateTruthy() internal Babel methods.

Note:

This is only exploitable if the attacker uses known affected plugins such as @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. No other plugins under the @babel/ namespace are impacted, but third-party plugins might be.

Users that only compile trusted code are not impacted.

Workaround

Users who are unable to upgrade the library can upgrade the affected plugins instead, to avoid triggering the vulnerable code path in affected @babel/traverse.
