CVE-2023-39331 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. A previously disclosed vulnerability (CVE-2023-30584) was patched insufficiently in commit 205f1e6. The new path traversal vulnerability arises because the implementation does not protect itself against the application overwriting built-in utility functions with user-defined implementations. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.. EPSS estimates a 1.32% chance of exploitation in the next 30 days.
