EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.7%, top 47% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

The decompress package for Node.js extracts archives. Prior to 10.2.1 and 11.1.3, archive extraction can create files and links outside the target directory. When extracting an archive to a directory, a crafted archive can read or write files outside that directory because hardlink and symlink entries are created without checking where targets point, path containment used a string prefix comparison, and file modes failed to remove setuid, setgid, or sticky bits. This issue is fixed in @xhmikosr/decompress versions 10.2.1 and 11.1.3.
