The Backup and Staging by WP Time Capsule plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 1.22.26 via the downloadrecentdecryptedfilewptc. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract download the most recently admin-decrypted SQL database backup, which typically contains password hashes, user credentials, and other sensitive site configuration data stored in the 'recentdecryptedfile' option. Exploitation requires that an administrator has previously performed a decrypt action, causing the decrypted SQL backup file to exist in the plugin's upload directory; without this prior admin action, there is no file to serve.

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.
