Passing a negative integer to Go's built-in make() function for slice allocation triggers an unrecoverable runtime panic (panic: len out of range).\n\nBecause the reader goroutine handles network I/O without an explicit recover() wrapper, this panic propagates up to the runtime root, abruptly terminating the host application.\n\n**Attack Vector / Exploitation Scenario**\nAn attacker capable of spoofing, compromising, or controlling an AMQP broker can exploit this flaw during two primary phases:\n\n1. Connection Establishment: Sending a malicious connection.start handshake frame containing server-properties with an 'x' type field assigned a negative length.\n2. Message Delivery: Delivering a message payload where the header table contains a malformed field matching the criteria above.\n\n**Impact**\nAvailability: High. A single malformed frame can reliably crash the client process, resulting in a persistent Denial of Service (DoS) if the client automatically reconnects and receives the same payload.","state":0,"publishedAt":"2026-09-17T17:04:29+00:00","modifiedAt":"2026-10-01T20:55:54.9756445+00:00","affected":[{"ecosystem":"Go","name":"github.com/rabbitmq/amqp091-go","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.13.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-4v58-74mf-rjx3","https://nvd.nist.gov/vuln/detail/CVE-2026-77412","https://github.com/rabbitmq/amqp091-go/pull/344","https://github.com/rabbitmq/amqp091-go/commit/669b42bf7b1db76bc6d4973e3634247f680accbf","https://github.com/rabbitmq/amqp091-go","https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0"],"sourceUrl":"https://github.com/advisories/GHSA-4v58-74mf-rjx3","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-4v58-74mf-rjx3","identifiers":["GHSA-4v58-74mf-rjx3","CVE-2026-77412","GO-2026-6494"]},"retained":false,"historicalAffected":[]},{"revision":"e7a8f2ef97254115b1e5877e0e029941","observedAt":"2026-10-24T13:19:41.952+00:00","statement":{"source":"osv","id":"GO-2026-6494","aliases":["CVE-2026-77412","GHSA-4v58-74mf-rjx3"],"title":"RabbitMQ amqp091-go: Denial of Service via Malicious Field Length in AMQP Client in github.com/rabbitmq/amqp091-go","description":"RabbitMQ amqp091-go: Denial of Service via Malicious Field Length in AMQP Client in github.com/rabbitmq/amqp091-go","state":0,"publishedAt":"2026-10-01T20:23:56+00:00","modifiedAt":"2026-10-01T20:45:11.2392527+00:00","affected":[{"ecosystem":"Go","name":"github.com/rabbitmq/amqp091-go","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.13.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[],"references":["https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-4v58-74mf-rjx3","https://nvd.nist.gov/vuln/detail/CVE-2026-77412","https://github.com/rabbitmq/amqp091-go/commit/669b42bf7b1db76bc6d4973e3634247f680accbf","https://github.com/rabbitmq/amqp091-go/pull/344","https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0"],"sourceUrl":"https://osv.dev/vulnerability/GO-2026-6494","license":"OSV · upstream source license applies","key":"osv:GO-2026-6494","identifiers":["GO-2026-6494","CVE-2026-77412","GHSA-4v58-74mf-rjx3"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
