RabbitMQ amqp091-go: Missing Explicit TLS Minimum Version Configuration In URI Parser

Published Sep 16, 2026 CVSS 4.0 · 9.4 Critical EPSS < 1% KEV · Not listed
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.
