What is CVE-2026-105447?
CVE-2026-105447 is a medium-severity missing authorization vulnerability in Red Hat Quay 3, published on 5 Oct 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
A flaw was found in Quay. When handling build trigger requests, the application incorrectly exposes trigger configuration details containing repository write tokens to global read-only administrative users. An authenticated user with read-only privileges can exploit this flaw by querying the build trigger API to retrieve these delegate tokens. This issue allows a restricted user to bypass read-only limitations and push arbitrary container images to private repositories, leading to privilege escalation.
