It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-77407 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/rabbitmq/amqp091-go (Go): affected all versions; fixed in 1.13.0\n- github.com/rabbitmq/amqp091-go (Go): affected all versions; fixed in 1.13.0\n- github.com/rabbitmq/amqp091-go (Go): affected all versions; fixed in 1.13.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-77407/ (Markdown: https://insights.sbomify.com/CVE-2026-77407/index.md)","id":"CVE-2026-77407","markdown":"https://insights.sbomify.com/CVE-2026-77407/index.md","name":"CVE-2026-77407","record":{"aliases":["AZL-103194","AZL-103278","CLEANSTART-2026-CK95490","CLEANSTART-2026-JZ39713","CLEANSTART-2026-LD19484","DEBIAN-CVE-2026-77407","ECHO-1f45-9931-8879","GHSA-27gv-rfvv-22mv","GO-2026-6491","MINI-259x-mm89-xhpj","MINI-262g-fx6j-vqm7","MINI-2grh-hr7x-cg75","MINI-2vrw-vwmf-8cq3","MINI-3m7x-q8j6-2wpw","MINI-3xxh-8ccq-3x3p","MINI-44xx-xv93-8gh8","MINI-5xr8-6mw6-wjw3","MINI-65jj-v4mh-8h35","MINI-6xc5-q7px-5jqq","MINI-89mw-c842-v28g","MINI-8fv7-4p52-c6gq","MINI-9979-c8cr-rrcw","MINI-9ph2-fj7v-878h","MINI-c7wx-whvx-wg3h","MINI-f6fw-44rh-9w2c","MINI-fc7q-5qq9-7mg8","MINI-ffvv-qhpm-cq6r","MINI-fq7h-fqhf-hqrx","MINI-g8f8-f55r-84pp","MINI-ggj4-ccw2-p4c9","MINI-h84w-6j9x-7j6w","MINI-hgv9-ccw7-h59j","MINI-j5hq-w7gc-jc79","MINI-jg2p-2xr6-74ww","MINI-jp92-3585-5xq5","MINI-mp2g-h46f-65mc","MINI-phg4-633c-22g3","MINI-pm76-q8pc-cmqr","MINI-pvp2-v9h6-wwc8","MINI-rjf7-x2g3-7gh5","MINI-wfc3-r2p9-4j8j","MINI-wm97-58r8-2jqf","MINI-wpmg-79fj-2pvp","MINI-wv8x-g4mj-m4v5","MINI-xwh7-ww76-59cw","ROOT-APP-GOBINARY-CVE-2026-77407","UBUNTU-CVE-2026-77407"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Go AMQP client library","requires_auth":"low_privilege","summary":"Attackers with access to application memory or logs can extract RabbitMQ credentials because the Go client library fails to clear plaintext passwords after authentication.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:H/SI:L/SA:L","version":"4.0"},"cwes":[{"id":"CWE-316","name":"Cleartext Storage of Sensitive Information in Memory"}],"description":"RabbitMQ amqp091-go is a Go AMQP 0.9.1 client.

The Connection.openComplete method in connection.go does not clear those values. Code with access to the Connection object, including reflective loggers, application performance monitoring agents, debugging utilities, and panic handlers, can traverse the configuration and expose the credentials to logs or state captures.
