GHSA-frrj-87jh-2772: GoBGP confederation validation panics on empty AS_PATH attributeCVE-2026-49838 0 GoBGP versions prior to 4.7.0 contain a vulnerability where a zero-length AS_PATH attribute in a BGP UPDATE message causes a panic during confederation eBGP validation. This occurs because the AS_PATH attribute decoder returns an empty value slice instead of an error for zero-length attributes, leading to an unchecked index access and a runtime panic. A remote unauthenticated confederation eBGP peer can exploit this by sending a malformed UPDATE with an empty AS_PATH, causing denial of service of the affected GoBGP process or peer session.
