Summary
Prior to 1.2.27, any authenticated MailWatch user, including the U, D, and H roles, can release to inbox or permanently delete the quarantined mail of any other user or domain by supplying an arbitrary message id to mailscanner/quarantine_action.php. The action does not check message ownership or apply the per-role global_filter, and message identifiers are enumerable.
Risk Assessment
A low-privilege user can force-deliver or permanently delete other users' or domains' quarantined messages, compromising mail confidentiality and integrity.
Recommendation
Update MailWatch for MailScanner to version 1.2.27 or later.

The Ultra Addons for Contact Form 7 plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the _getObjAttr function in all versions up to, and including, 3.5.54. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). This requires the PDF Generator add-on to be active and a Contact Form 7 form to be configured for PDF generation.
Original NVD description (English source)
MailWatch for MailScanner is a web-based front-end to MailScanner. Prior to 1.2.27, any authenticated MailWatch user, including the U/user, D/domain-admin, and H/host roles, can release to inbox or permanently delete the quarantined mail of any other user or domain by supplying an arbitrary message `id` to `mailscanner/quarantine_action.php`. The action path calls `quarantine_list_items()` in `mailscanner/functions.php`, which selects from `maillog` by the supplied identifier without the per-role `global_filter` applied by listing and read views. The action requires a valid session and CSRF token, but the caller can submit a token from the caller's own session; ownership of the requested message is never checked. Message identifiers are enumerable, allowing a low-privilege user to invoke `quarantine_release()` or `quarantine_delete()` for other users' or domains' quarantined messages, force-delivering mail held by the quarantine or permanently deleting it. This issue is fixed in version 1.2.27.
