Advanced File Manager 5.4.13 - 5.4.14 - Authenticated Stored XSS via SVG Sanitiser Content-Sniff Bypass

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 Advanced File Manager WordPress plugin before 6.0.0 does not correctly determine whether a stored file is an SVG before sanitising it, allowing users granted file-manager access by an administrator to store a file containing script that is not stripped and that runs in the browser of anyone who opens it, including an administrator.
