CVE-2026-105447

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.
