eaSYNC < 1.3.31 - Unauthenticated Cancellation Request Creation and Email Template Update

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 eaSYNC Booking WordPress plugin before 1.3.31 does not perform authorization or nonce checks on several of its cancellation-related AJAX actions, allowing unauthenticated users to create booking cancellation requests, trigger booking notification emails, and overwrite the content of the emails the site sends.
