CVE-2026-19725: Unknown Wpvivid — Backup, Migration & Staging

Critical severity, CVSS 9.1. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Unknown Wpvivid — Backup, Migration & Staging: before 0.9.131 (fixed in 0.9.131)
