A vulnerability exists in Red Hat Quay's notification webhook feature, where the Slack and generic webhook handlers improperly accept user-supplied URLs without proper SSRF validation. This flaw allows a repository administrator to exploit the Quay worker to send POST requests to internal network addresses or cloud endpoints, potentially exposing sensitive infrastructure. Organizations using Red Hat Quay, particularly those with sensitive internal services, should prioritize addressing this issue to mitigate the risk of unauthorized access.
