What is CVE-2026-82194?

A vulnerability exists in the WPvivid Backup, Migration & Staging plugin for WordPress prior to version 0.9.134, allowing unauthorized file deletions. The plugin fails to properly validate user-supplied paths in its file deletion routine. As a result, an attacker, potentially an administrator, can delete arbitrary files from the server, including those outside the web root directory. This poses a significant risk to server integrity and data security, highlighting the importance of keeping plugin versions updated and implementing strict access controls.
