Prior to 1.13.0, the writeShortstr function in write.go casts the byte length of AMQP shortstr property values to uint8 without first rejecting values longer than 255 bytes. An application that accepts an oversized CorrelationId, ReplyTo, MessageId, Expiration, UserId, AppId, ContentType, ContentEncoding, or Type value can therefore serialize a wrapped length and only a truncated prefix, while reporting no error. The resulting silent metadata corruption can break request and reply correlation, routing, tracing, and downstream message processing. This issue is fixed in version 1.13.0.","state":0,"publishedAt":"2026-09-16T15:17:49.747+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:L/VI:H/VA:H/SC:L/SI:H/SA:L/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":9.1,"severity":"CRITICAL"}],"references":["https://github.com/rabbitmq/amqp091-go/commit/6959423aa2784a1971e399175dfb2065dea0f3b0","https://github.com/rabbitmq/amqp091-go/pull/354","https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0","https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-j497-x9hr-x34x"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77408","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-190"],"productCriteria":[],"sourceDates":{"published":"2026-09-16T15:17:49.747","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.
