CVE-2026-114399
HIGH 7Trudesk through 1.2.11 contains a path traversal vulnerability that allows administrators to delete arbitrary files by supplying encoded traversal sequences to DELETE /api/v1/backup/:backup. Attackers can also pass unvalidated file values to POST /api/v1/backup/restore to restore archives from, or extract to, paths outside the intended directories.
Severe if exploited (CVSS 7), but no known exploitation and low modeled probability. Patch on a normal cadence.
