The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to arbitrary file uploads due to a missing capability check on the wpvivid_upload_import_files and wpvivid_upload_files AJAX actions that allows low-level authenticated attackers to upload zip files that can be subsequently extracted. This affects versions up to, and including 0.9.35.
The Hunk Companion WordPress plugin before 1.9.0 does not correctly authorize some REST API endpoints, allowing unauthenticated requests to install and activate arbitrary Hunk Companion WordPress plugin before 1.9.0 from the WordPress.org repo, including vulnerable Hunk Companion WordPress plugin before 1.9.0 that have been closed.
