BackWPup < 5.7.7 - Admin+ Path Traversal to RCE via Restore PclZip Fallback
The BackWPup WordPress plugin before 5.7.7 does not properly restrict the destination path of files extracted during a backup restore when its fallback archive library is used, allowing high-privileged users to write files outside the intended restore directory, potentially leading to remote code execution.
