high 7.2 CVE-2026-111577 · published 2026-10-28

Privilege escalation in GoSMTP (older than 1.2.5)

Affected: older than 1.2.5
Fixed in: 1.2.5
Access needed (per CVSS): Needs an admin-level account
Range from: CVE record (the advisory publisher) · score by CISA ADP

Details from the advisory

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.
