{"id":"CVE-2026-77405","published":"2026-09-16T15:17:47.980","lastModified":"2026-09-18T18:17:14.820","description":"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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-326"],"vendors":[],"products":[],"references":[{"url":"https://github.com/rabbitmq/amqp091-go/commit/c9fd433ecac2e557919e51acc9d809390c402c6e","tags":[]},{"url":"https://github.com/rabbitmq/amqp091-go/pull/355","tags":[]},{"url":"https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0","tags":[]},{"url":"https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-33mj-cw25-m34h","tags":[]}],"exploitRefs":[{"url":"https://github.com/rabbitmq/amqp091-go/commit/c9fd433ecac2e557919e51acc9d809390c402c6e","tags":[]},{"url":"https://github.com/rabbitmq/amqp091-go/pull/355","tags":[]},{"url":"https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0","tags":[]},{"url":"https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-33mj-cw25-m34h","tags":[]}],"hasPoc":true,"ai":null}
