The fix

We hold no Microsoft remediation data for CVE-2026-115242, which normally means it is not a Windows CVE. For non-Microsoft software the fix is the vendor's own updated release, and the affected versions are listed below.

What it is

The WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.137 does not sanitize the staging destination folder supplied to its staging-start handler, applying only a generic text filter while the sibling writability-check handler applies the correct filename sanitizer, so an authenticated administrator can supply a path containing traversal sequences and make the WPvivid — Backup, Migration & Staging WordPress plugin before 0.9.137 write the copied site files outside the WordPress installation directory.
