When the AWS_ALB key provider is configured, the resolver constructs the key-fetch URL by directly concatenating the attacker-controlled kid header value from an inbound JWT without sanitizing path traversal characters or query-string separators. This allows an unauthenticated remote attacker to force the application server to issue GET requests to arbitrary paths on the same origin as the configured key endpoint. As a result, non-public endpoints or internal data reachable on that origin may be read by the attacker before JWT signature verification takes place.","state":0,"publishedAt":"2026-09-17T14:01:30.083+00:00","modifiedAt":"2026-10-09T16:26:17.785+00:00","affected":[{"ecosystem":"https://access.redhat.com/jbossnetwork/restricted/listSoftware.html","name":"quarkus-smallrye-jwt","ranges":[],"versions":[],"rawVersionEvidence":"{\n
