This vulnerability allows a user with organization repository administrative privileges and the FEATURE_BUILD_SUPPORT enabled to read arbitrary files on the build worker. This is possible due to insufficient validation of the build source configuration, which permits the use of a file:// Uniform Resource Identifier (URI) scheme. Exploiting this flaw can lead to unauthorized information disclosure."], "mitigation": {"lang": "en:us", "value": "To reduce exposure, disable the FEATURE_BUILD_SUPPORT feature in Red Hat Quay if it is not actively used.

A user with organization repository admin privileges and the `FEATURE_BUILD_SUPPORT` enabled can exploit a lack of scheme validation in the custom build trigger handler. This allows for local file inclusion via the `file://` URI scheme, leading to the disclosure of arbitrary files accessible to the build worker process.", "threat_severity": "Important"}
