{"id":"CVE-2026-77405","summary":"RabbitMQ amqp091-go: Missing Explicit TLS Minimum Version Configuration In URI Parser","details":"RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, tlsConfigFromURI in uri.go creates tls.Config values without setting MinVersion to tls.VersionTLS12. Builds using a Go runtime whose default permits TLS 1.0 or TLS 1.1 can therefore negotiate an obsolete protocol version when connecting through an amqps URI. A network attacker able to influence TLS negotiation with such a legacy build may weaken transport protection for AMQP messages and credentials. This issue is fixed in version 1.13.0.","aliases":["GHSA-33mj-cw25-m34h"],"modified":"2026-09-19T03:30:34.745515049Z","published":"2026-09-16T14:42:08.670Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77405.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-326"]},"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/2026/77xxx/CVE-2026-77405.json"},{"type":"ADVISORY","url":"https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-33mj-cw25-m34h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77405"},{"type":"FIX","url":"https://github.com/rabbitmq/amqp091-go/commit/c9fd433ecac2e557919e51acc9d809390c402c6e"},{"type":"FIX","url":"https://github.com/rabbitmq/amqp091-go/pull/355"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rabbitmq/amqp091-go","events":[{"introduced":"0"},{"fixed":"c9fd433ecac2e557919e51acc9d809390c402c6e"},{"fixed":"d26d57e952cc61554ea9c54bd676c8f40ed0d84d"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.13.0"}],"source":["AFFECTED_FIELD","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-2026-77405.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:H/SI:L/SA:N"}]}
