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.","published":"2026-09-16T15:17:47.980","modified":"2026-09-16T15:17:47.980","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/rabbitmq/amqp091-go/commit/c9fd433ecac2e557919e51acc9d809390c402c6e","label":"rabbitmq/amqp091-go@c9fd433"},"references":[{"type":"WEB","url":"https://github.com/rabbitmq/amqp091-go/commit/c9fd433ecac2e557919e51acc9d809390c402c6e"},{"type":"WEB","url":"https://github.com/rabbitmq/amqp091-go/pull/355"},{"type":"WEB","url":"https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0"},{"type":"WEB","url":"https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-33mj-cw25-m34h"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-16T15:17:47.980"}}
