- Severity: CVSS 9.1 (Critical), CISA-ADP
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
- CISA SSVC: exploitation=poc, automatable=yes, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 0.9.131
- Published: 2026-08-16 · Updated: 2026-08-17

## Affected

- Unknown WPvivid — Backup, Migration & Staging: fixed in 0.9.131

## 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.
