Popup Builder < 4.4.6 - Unauthenticated Popup Trashing via post_type Parameter

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 Popup Builder WordPress plugin before 4.4.6 does not perform authorization checks before trashing popup content in a maintenance routine that runs on unauthenticated requests, allowing unauthenticated attackers to move affected popups into the Trash and overwrite their stored preview data.
