From version 2.0.0 to before version 5.0.0, any authenticated Wallos user (no admin rights required) can make the server open arbitrary outbound SMTP connections to internal/link-local addresses, by setting the SMTP host of their personal email notifications to an internal IP. The per-user notification settings endpoint (endpoints/notifications/saveemailnotifications.php) performs no SSRF validation, and the notification cron (endpoints/cronjobs/sendnotifications.php) feeds that user-controlled host straight into PHPMailer ($mail->Host = $email['smtpAddress']). When the user's subscription notification fires, the server connects to the chosen host:port. This issue has been patched in version 5.0.0."}],"source":{"advisory":"GHSA-c75x-9vj6-57qj","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-09-01T14:15:10.690747Z","id":"CVE-2026-77352","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-01T14:57:40.014Z"}}]}}
