CVE-2026-54414
Last modified
CVE-2026-54414 is a critical-severity vulnerability rated 9.8/10 on the CVSS scale. FileRise before 3.16.0 is vulnerable to path traversal in the shared-folder upload endpoint (/api/folder/uploadToSharedFolder.php), leading to arbitrary file write and administrator account takeover. The upload filename is validated by FolderController with basename and REGEX_FILE_NAME, which permit URL-encoded sequences (the regex blocks / and \ but not %).. EPSS estimates a 1.09% chance of exploitation in the next 30 days.
