Description

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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • Unknown BackWPup — Before 5.7.7
