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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
| Vendor | Product | Default status | Versions | ||||||
