stated backup_and_staging_by_wp_time_capsule · vendor revmakx backup_and_staging_by_wp_time_capsule

The Backup and Staging by WP Time Capsule plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the the UploadHandler.php file and no direct file access prevention in all versions up to, and including, 1.22.21. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. VulnCheck canary evidence.
