Document Gallery <= 5.1.1 - Reflected XSS via data-shortcode Attribute

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 Document Gallery WordPress plugin through 5.1.1 does not properly sanitise and escape user input before reflecting it inside an HTML attribute in the response of an unauthenticated AJAX action, leading to a Reflected Cross-Site Scripting vulnerability which can be exploited against any visitor, including a logged-in administrator.
