Description

This security bulletin contains information about 1 vulnerability.


1) Path traversal (CVE-ID: CVE-2026-49342)

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

CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to path traversal in static cache lookup when handling request paths before router path cleanup. A remote attacker can send a specially crafted request containing parent-directory components to disclose sensitive information.

Only deployments with a configured document root are vulnerable, and only readable regular files reachable through the forced .html suffix can be returned.
