Summary
A flaw was found in Red Hat Quay. A user with FEATURE_BUILD_SUPPORT enabled and repository write access can exploit a Server-Side Request Forgery (SSRF) vulnerability within the build API.
This allows the user to provide a malicious URL, causing the Quay builder to make requests to internal network addresses. Such an action could lead to the disclosure of sensitive internal information.
Exploitation requires specific configuration and privileges, limiting the attack surface. Successful exploitation could enable access to internal network resources from the Quay builder.
