{"id":"CVE-2026-79921","summary":"amqp091-go has a Potential Memory Exhaustion/Protocol Violation via Broker-Controlled Oversized Payload","details":"amqp091-go is a Go AMQP 0.9.1 client. Before version 1.13.0, a compromised or malicious AMQP broker can force the client to allocate resources for and process content body frames that exceed the negotiated frame_max limit. This can lead to unexpected memory consumption or application-layer denial of service (DoS), bypassing the protocol's built-in framing constraints. Version 1.13.0 contains a fix. No known workarounds are available.","aliases":["GHSA-6c5v-hqjr-5xxp"],"modified":"2026-08-30T03:30:47.392857561Z","published":"2026-08-26T20:24:58.115Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/79xxx/CVE-2026-79921.json"},"references":[{"type":"WEB","url":"https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/79xxx/CVE-2026-79921.json"},{"type":"ADVISORY","url":"https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-6c5v-hqjr-5xxp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-79921"},{"type":"FIX","url":"https://github.com/rabbitmq/amqp091-go/commit/6beb7b51f59e46ddcf8066ad498dad32491d3be0"},{"type":"FIX","url":"https://github.com/rabbitmq/amqp091-go/pull/353"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rabbitmq/amqp091-go","events":[{"introduced":"0"},{"fixed":"d26d57e952cc61554ea9c54bd676c8f40ed0d84d"},{"fixed":"6beb7b51f59e46ddcf8066ad498dad32491d3be0"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.13.0"}],"source":["DESCRIPTION","REFERENCES"]}}],"versions":["v1.12.0","v1.11.0","v1.10.0","v1.9.0","v1.8.1","v1.8.0","v1.7.0","v1.6.1","v1.6.1-rc.2","v1.6.1-rc.1","v1.6.0","v1.5.0","v1.4.0","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.0","v1.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-79921.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
