CVE-2026-8996

Description

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 download_recent_decrypted_file_wptc. 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 'recent_decrypted_file' 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.
