An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-103764 exists.\n\nAffected product: kvcache-ai Mooncake. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-103764/ (Markdown: https://insights.sbomify.com/CVE-2026-103764/index.md)","id":"CVE-2026-103764","markdown":"https://insights.sbomify.com/CVE-2026-103764/index.md","name":"CVE-2026-103764","record":{"aliases":["GHSA-mp8g-r7h2-5x36"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"KV cache transfer engine","requires_auth":"none","summary":"Unauthenticated attackers can read or write arbitrary process memory via crafted TCP packets, potentially disclosing secrets or executing code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-822","name":"Untrusted Pointer Dereference"}],"description":"Mooncake transfer engine before 0.3.13 contains an untrusted pointer dereference in ServerSession::readHeader that allows unauthenticated attackers to read and write arbitrary process memory via the TCP transport data port.
