Prior to 1.13.0, readLongstr in read.go returns an empty string and a nil error when a declared AMQP longstr length exceeds 0x7FFFFFFF instead of returning ErrSyntax. The function leaves the declared field bytes unread, while readTable treats the operation as successful and continues parsing from the wrong offset. A malicious or compromised broker can provide an oversized longstr in a table field and desynchronize subsequent AMQP parsing, causing attacker-controlled trailing bytes to be interpreted as later fields or frames and disrupting connection integrity and availability. This issue is fixed in version 1.13.0.","state":0,"publishedAt":"2026-09-16T15:17:50.563+00:00","modifiedAt":"2026-09-23T18:19:19.803+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":9.5,"severity":"CRITICAL"}],"references":["https://github.com/rabbitmq/amqp091-go/commit/143c1ace5fa7344cee135e5c7d22970f0de68282","https://github.com/rabbitmq/amqp091-go/pull/347","https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0","https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-c5pq-fr2g-9jpf"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77411","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-754"],"productCriteria":[],"sourceDates":{"published":"2026-09-16T15:17:50.563","lastModified":"2026-09-23T18:19:19.803"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
