Description

This security bulletin contains information about 1 vulnerability.


1) Path traversal (CVE-ID: CVE-2026-6321)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass path-based policy checks.

The vulnerability exists due to path traversal in the normalize() and equal() functions when processing percent-encoded path separators and dot segments in attacker-controlled URLs. A remote attacker can supply a specially crafted URL to bypass path-based policy checks.

Applications that normalize or compare attacker-controlled URLs to enforce path-based policy are affected.
