Modern Events Calendar Lite < 7.36.4 - Subscriber+ Arbitrary Post Modification via IDOR

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 Modern Events Calendar Lite WordPress plugin before 7.36.4 does not verify that a user is authorized to edit the target post before updating it, allowing authenticated users with the Subscriber role to modify the title, content, and excerpt of arbitrary posts, pages, and custom post types created by other users.
