CVE-2022-27844Network attack vector

Authenticated file read via unvalidated log filename

Published Apr 11, 2022 · Updated Apr 28, 2026

Arbitrary file read in WPvivid Backup & Migration 0.9.70 and earlier allows remote authenticated users to download server files. The log-file download path accepts a requested filename without properly validating that it remains within the intended log set, then returns the referenced file. Administrator-level WordPress access is required, and the demonstrated consequence is disclosure of server-readable file contents.
