{"cve":"CVE-2026-77405","nvd":{"published":"2026-09-16T15:17:47.980","modified":"2026-09-24T21:16:28.120","status":"Awaiting Analysis","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.","cvss_v4":{"vector":"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","score":9.4},"cvss_v3":null,"cwes":["CWE-326"],"references":["https://github.com/rabbitmq/amqp091-go/commit/c9fd433ecac2e557919e51acc9d809390c402c6e","https://github.com/rabbitmq/amqp091-go/pull/355","https://github.com/rabbitmq/amqp091-go/releases/tag/v1.13.0","https://github.com/rabbitmq/amqp091-go/security/advisories/GHSA-33mj-cw25-m34h"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-77405","score":0.00282,"percentile":0.2073,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-33mj-cw25-m34h","url":"https://osv.dev/vulnerability/GHSA-33mj-cw25-m34h","summary":"RabbitMQ amqp091-go: Missing Explicit TLS Minimum Version Configuration In URI Parser","modified":"2026-10-01T20:56:07.689506743Z","packages":[{"ecosystem":"Go","name":"github.com/rabbitmq/amqp091-go","purl":"pkg:golang/github.com/rabbitmq/amqp091-go","ranges":["<1.13.0"],"fixed":["1.13.0"]}]},{"id":"GO-2026-6492","url":"https://osv.dev/vulnerability/GO-2026-6492","summary":"RabbitMQ amqp091-go: Missing Explicit TLS Minimum Version Configuration In URI Parser in github.com/rabbitmq/amqp091-go","modified":"2026-10-01T20:45:11.303878798Z","packages":[{"ecosystem":"Go","name":"github.com/rabbitmq/amqp091-go","purl":"pkg:golang/github.com/rabbitmq/amqp091-go","ranges":["<1.13.0"],"fixed":["1.13.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
