Short explanation
The WPvivid — Backup, Migration & Staging WordPress plugin before version 0.9.137 fails to properly validate file extensions during import uploads. This allows an authenticated administrator to store files with arbitrary extensions in the import directory, serving as an incomplete fix for CVE-2025-5961.
Allowing authenticated administrators to upload files with arbitrary extensions poses severe risks regarding system compromise and unauthorized code execution.
What should be done?
- Follow vendor advisories for updates.
- Apply security patches when available.
- Review plugin configurations and permissions.

Show the technical text from the sources
The WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.137 does not validate the extension of the file it actually stores when handling an import upload: it checks the extension of a separate request field while saving the uploaded file itself with WordPress's upload type-checking disabled, so an authenticated administrator can store a file with an arbitrary extension, including a PHP file, in the WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.137's import directory. This is an incomplete fix of CVE-2025-5961, whose extension check was applied to the wrong value.
