What is CVE-2026-115426?

The WPvivid Backup, Migration & Staging WordPress plugin before version 0.9.138 fails to validate the backup storage directory path adequately. This security lapse allows administrators to create directories and files outside the designated backup location through a path traversal attack, potentially leading to unauthorized access and data leakage. It is crucial for users to update to a secure version to mitigate this risk.

Affected Version(s)

WPvivid — Backup, Migration & Staging 0 < 0.9.138
