CVE-2026-86828 Details
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.
A path traversal vulnerability has been identified in the BackWPup WordPress plugin, affecting versions prior to 5.7.7. The issue arises because the plugin's fallback archive library does not properly restrict the destination path of files extracted during backup restoration. This flaw allows high-privileged users to write files outside the designated restore directory, potentially leading to remote code execution.
Users are advised to update the BackWPup WordPress plugin to version 5.7.7 or later.
