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-2026-77404 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-2026-77404/ (Markdown: https://insights.sbomify.com/CVE-2026-77404/index.md)","id":"CVE-2026-77404","markdown":"https://insights.sbomify.com/CVE-2026-77404/index.md","name":"CVE-2026-77404","record":{"aliases":["CLEANSTART-2026-OF14206","CLEANSTART-2026-PW36869","CLEANSTART-2026-TU13335","DEBIAN-CVE-2026-77404","ECHO-b336-8e7c-32ba","GHSA-465g-fh3v-9jw4","GO-2026-6493","MINI-28wf-jqj4-w428","MINI-3hr4-h8hh-cghr","MINI-4x2r-hx7r-x6v7","MINI-4xwr-v243-mvj2","MINI-5ppc-82cw-j4p7","MINI-5q98-m5r5-7ghh","MINI-67rr-whcm-99wm","MINI-6gmx-qp44-h5x4","MINI-6p2m-c86v-rgq6","MINI-6qgw-j3gx-4mxw","MINI-8fmx-xj8m-p3mc","MINI-9mpw-cfgr-vwfm","MINI-9x26-84hj-mcp8","MINI-cfc5-wg65-gx7w","MINI-cmr9-4v7p-95gw","MINI-cqc7-9cjm-pwf5","MINI-f3cw-h665-7532","MINI-f826-hrr3-hwgr","MINI-g2x9-c3c6-j5ff","MINI-gr93-387f-hgx3","MINI-h6x9-89rc-qfgx","MINI-hwph-j427-ghc2","MINI-j2hq-hvrv-6394","MINI-m2gw-jmh2-hwqc","MINI-m6fx-chwg-qwwc","MINI-m789-hvw8-8crc","MINI-mcfv-fp66-6pwc","MINI-qjvv-f65w-5p88","MINI-rjmw-96pr-h4vx","MINI-rxwc-x7g6-96vx","MINI-v9cj-rrcv-jhpq","MINI-vh69-mrr6-grm9","MINI-vw85-g676-6gf8","MINI-x4xq-7jhx-ph35","MINI-x97g-5qmj-2pcf","MINI-xw47-gp9r-cch4","ROOT-APP-GOBINARY-CVE-2026-77404","UBUNTU-CVE-2026-77404"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass","other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Go AMQP client library","requires_auth":"low_privilege","summary":"Attackers can inject delimiters into TLS paths to overwrite connection options, potentially selecting unintended cryptographic assets or corrupting configuration.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:L","version":"4.0"},"cwes":[{"id":"CWE-116","name":"Improper Encoding or Escaping of Output"}],"description":"RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, URI.String in uri.go concatenates CertFile, KeyFile, CACertFile, and ServerName values directly into an AMQPS query string instead of encoding them as URL query parameters with url.Values. If an application accepts a TLS asset path containing ampersand or equals delimiters and later reparses the serialized URI with ParseURI, the embedded delimiters can create or overwrite connection options, including paths to TLS certificate, key, or CA files. This can corrupt connection configuration or select unintended local cryptographic assets.
