——7The 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.1d CVE-2026-1217335.4 MÉD

——11The BuddyBoss App plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.2.1 via the send_feedback function. This is due to insufficient file type validation that relies solely on the client-supplied Content-Type header without server-side content inspection or extension validation. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. While uploaded files are deleted after email transmission, a race condition exists during SMTP execution that allows access to the file, and files persist indefinitely when wp_mail() fails.2d
