Unauthenticated attackers can perform file operations on project media directories including creating directories, uploading files, renaming files, duplicating files, overwriting files, and deleting files, which can be chained with path traversal and extension blocklist vulnerabilities to achieve remote code execution and arbitrary file read.","published":"2026-04-22T19:17:03.000Z","lastModified":"2026-10-26T22:10:00.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":8.8,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-497"],"affected":[],"epss":{"score":0.0311,"percentile":0.87702,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (3.11%).
