CVE-2026-19725

critical

Description

The WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.131 does not sanitise a value taken from an unauthenticated request before using it to build a log file path, allowing an attacker holding a site to site transfer key to create a log file in any existing writable directory of the site, including the web root. The file name always carries a fixed suffix and the contents are always the WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.131's own log header, so only the location of the file is attacker controlled.
