The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

A flaw in Node.js Permission Model filesystem enforcement leaves fs.realpathSync() without the required read permission checks. This is an incomplete fix of CVE-2026-21715, which only covered fs.realpathSync.native().
As a result, code running under --permission with restricted --allow-fs-read can still use fs.realpathSync() to check file existence, resolve symlink targets, and enumerate filesystem paths outside of permitted directories.
This vulnerability affects Node.js 26.x, 24.x, and 22.x.
