Malcure Malware Shield < 19.9.7 - Multisite Subsite Admin+ Arbitrary File Write and Deletion via wpmr_ajax_request

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 Malcure Malware Shield — Removal, Repair, Monitor WordPress plugin before 19.9.7 does not perform an authorisation check on one of its AJAX actions, allowing users with a subsite administrator role on a multisite network to write and delete arbitrary files in the network's shared filesystem, which can lead to remote code execution.
