Ketello: katello content view history api cross-organization authorization 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.

A flaw was found in Katello where the Content View History API does not properly enforce authorization when accessing a Content View specified by the user. An authenticated user with permission to view Content Views in one organization may be able to access the lifecycle history of a Content View belonging to another organization by supplying its identifier to the affected API endpoint. This can result in unauthorized disclosure of Content View lifecycle information, including publication and promotion events, associated users, and timestamps.
