How to fix?

There is no fixed version for RHEL:8 nodejs:20/nodejs.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs:20/nodejs package and not the nodejs:20/nodejs package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

An incomplete fix for CVE-2024-36137 leaves FileHandle.chmod() and FileHandle.chown() in the promises API without the required permission checks, while their callback-based equivalents (fs.fchmod(), fs.fchown()) were correctly patched.

As a result, code running under --permission with restricted --allow-fs-write can still use promise-based FileHandle methods to modify file permissions and ownership on already-open file descriptors, bypassing the intended write restrictions.

This vulnerability affects 20.x, 22.x, 24.x, and 25.x processes using the Permission Model where --allow-fs-write is intentionally restricted.
