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.

Piranha CMS through 12.2 contains a missing authorization vulnerability in the Piranha.Manager LanguageApiController that allows any authenticated manager user to list, create, edit and delete site languages without the granular Language, LanguageAdd, LanguageEdit or LanguageDelete permissions. Attackers can call the manager/api/language Get, Save and Delete actions directly to remove languages and reassign sites to the default, affecting localized content instance-wide.
