An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-107386 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 1.14.0\n- github.com/rabbitmq/amqp091-go (Go): affected all versions; fixed in 1.14.0\n- github.com/rabbitmq/amqp091-go (Go): affected all versions; fixed in 1.14.0\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-2026-107386/ (Markdown: https://insights.sbomify.com/CVE-2026-107386/index.md)","id":"CVE-2026-107386","markdown":"https://insights.sbomify.com/CVE-2026-107386/index.md","name":"CVE-2026-107386","record":{"aliases":["CLEANSTART-2026-BX72159","CLEANSTART-2026-VR61817","CLEANSTART-2026-ZB44736","DEBIAN-CVE-2026-107386","ECHO-a87c-d3c1-0535","GHSA-w6r9-248c-frg8","GO-2026-6700","MINI-3cq2-56pp-8c53","MINI-3g3g-vhw3-r25f","MINI-3xm3-69f7-fch3","MINI-4p54-976j-x65x","MINI-53vv-37h9-v6mj","MINI-7fcr-jrxc-c38w","MINI-84p8-w4m2-9w96","MINI-87v4-rqqr-mcr7","MINI-8c39-24p8-956r","MINI-9273-2g7v-62vp","MINI-fwwp-2gwj-5cww","MINI-g84c-7q92-h329","MINI-hw6m-55rr-xv3q","MINI-j9h6-9f2m-2v2m","MINI-jg59-2p92-x48q","MINI-mfq8-327h-rrwg","MINI-mq7g-g2qm-h8w3","MINI-p5px-gmm5-4prm","MINI-p72f-j42h-fw9q","MINI-q4r6-w7q7-ffg2","MINI-q5c6-cvj5-6xxv","MINI-v323-hrw7-cjh3","MINI-w289-c24f-6593","MINI-x6gq-7522-h88m","UBUNTU-CVE-2026-107386"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go AMQP client library","requires_auth":"none","summary":"A malicious AMQP peer can cause memory exhaustion and crash the client process by bypassing frame size limits before connection negotiation completes.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"amqp091-go is a Go AMQP 0.9.1 client. From 1.13.0 until 1.14.0, the frame-size mitigation from the prior allocation advisory can be bypassed before connection.tune completes because Connection.maxFrameSize uses zero for both the not-yet-negotiated and negotiated-unlimited states. A malicious or compromised AMQP peer can send a short body-frame header with a large declared payload length, causing ReadFrame and the body-frame parser to allocate attacker-selected memory before the payload is received or the frame's protocol state is rejected. The condition is reachable through public Open even when Config.FrameSize is set to the protocol minimum and can cause severe memory pressure, out-of-memory termination, or loss of the client process before authentication completes.
