NewCVE-2026-77405 (opens in a new tab)How to fix?
There is no fixed version for Echo:latest golang-github-rabbitmq-amqp091-go.
NVD Description
Note: Versions mentioned in the description apply only to the upstream golang-github-rabbitmq-amqp091-go package and not the golang-github-rabbitmq-amqp091-go package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
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.
