      <title>CVE-2026-85749 — MailWatch: IDOR lets any authenticated user release or delete another tenant's quarantined mail</title>
      <link>https://db.gcve.eu/vuln/cve-2026-85749</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; MailWatch&lt;/p&gt;
&lt;p&gt;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&amp;#39;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&amp;#39; or domains&amp;#39; quarantined messages, force-delivering mail held by the quarantine or permanently deleting it. This issue is fixed in version 1.2.27.&lt;/p&gt;</description>
