Prior to 1.13.0, Connection.openTune in connection.go accepts a server-advertised FrameMax below the AMQP frameMinSize value of 4096 bytes because the connection negotiation loop does not enforce the protocol minimum. A malicious or compromised AMQP broker can therefore advertise an extremely small FrameMax, causing later client publications to be fragmented into excessive numbers of frames and write operations. This can consume CPU and stall the client or its host. This issue is fixed in version 1.13.0.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","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":8.9,"severity":null}],"references":["https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-xwwf-m8fg-p9q2","https://github.com/rabbitmq/amqp091-go/pull/353","https://github.com/rabbitmq/amqp091-go/commit/2e0a919b89f337dbf58db2bb34ab206dac354a06","https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-80807","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 16, 2026, 2:36:19 PM","dateUpdated":"Sep 16, 2026, 3:43:19 PM"},"relatedAdvisories":[{"id":"RHSA-2026:68290","title":"Red Hat Security Advisory: Red Hat Hardened Images RPMs bug fix and enhancement update","vulnerabilityIds":["CVE-2026-63209","CVE-2026-77403","CVE-2026-77404","CVE-2026-77406","CVE-2026-77407","CVE-2026-77409","CVE-2026-77410","CVE-2026-77412","CVE-2026-81872","CVE-2026-93450"]},{"id":"RHSA-2026:77656","title":"Red Hat Security Advisory: Red Hat Quay 3.9.27","vulnerabilityIds":["CVE-2026-17106","CVE-2026-49825","CVE-2026-54770","CVE-2026-59879","CVE-2026-77403","CVE-2026-77404","CVE-2026-77406","CVE-2026-77409","CVE-2026-77410","CVE-2026-77412","CVE-2026-79921","CVE-2026-82417","CVE-2026-84292","CVE-2026-84394","CVE-2026-87776"]},{"id":"RHSA-2026:79546","title":"Red Hat Security Advisory: Red Hat Quay 3.12.23","vulnerabilityIds":["CVE-2026-17106","CVE-2026-49825","CVE-2026-54770","CVE-2026-59879","CVE-2026-77403","CVE-2026-77404","CVE-2026-77406","CVE-2026-77409","CVE-2026-77410","CVE-2026-77412","CVE-2026-79921","CVE-2026-82417","CVE-2026-87776","CVE-2026-94603"]},{"id":"RHSA-2026:79366","title":"Red Hat Security Advisory: Red Hat Quay 3.10.27","vulnerabilityIds":["CVE-2026-49825","CVE-2026-54770","CVE-2026-59879","CVE-2026-77403","CVE-2026-77404","CVE-2026-77406","CVE-2026-77409","CVE-2026-77410","CVE-2026-77412","CVE-2026-79921","CVE-2026-82417","CVE-2026-87776"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
