CVE-2026-61718Network attack vector

Job cache deletion via bypassed authorization

Published Jul 16, 2026 · Updated Jul 16, 2026

Improper authorization in Bunkerity BunkerWeb 1.6.2 through 1.6.11 allows remote authenticated users to delete job cache files. BiscuitMiddleware treats /cache/ as a static-asset prefix and skips the write-permission check, while POST /cache/delete enforces login only. Exploitation requires a provisioned BunkerWeb PRO reader account and can purge security data, trigger a reload, and temporarily weaken WAF protection.
