Contact Form by Supsystic < 1.11.1 - Arbitrary Plugin Settings Update via CSRF

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

The Contact Form by Supsystic WordPress plugin before 1.11.1 does not verify a CSRF nonce before saving its mail settings, allowing an attacker to overwrite the site's outbound mail configuration, including the SMTP server, its credentials and the notification recipient, by tricking a logged-in administrator into visiting a crafted page, which can route the Contact Form by Supsystic WordPress plugin before 1.11.1's contact-form notifications through infrastructure the attacker controls.
