- CVE-2026-111577, 28 Oct 2026
- The GoSMTP WordPress plugin before 1.2.5 does not perform a settings-management authorization check on its SMTP configuration page, which is gated only on the GoSMTP WordPress plugin before 1.2.5-activation capability, allowing users with a delegated role below administrator to change outbound mail delivery and achieve administrator account takeover. CVE record
What to do if you run GoSMTP
If you run GoSMTP, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
