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-2026-11624/ (Markdown: https://insights.sbomify.com/CVE-2026-11624/index.md)","id":"CVE-2026-11624","markdown":"https://insights.sbomify.com/CVE-2026-11624/index.md","name":"CVE-2026-11624","record":{"aliases":["GHSA-76g7-m3xw-x9gr","GO-2026-6288"],"analysis":null,"analysis_generated_by":null,"assigner":"Google","cpe":[],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-346","name":"Origin Validation Error"}],"description":"The Model Context Protocol has a security warning advising servers to validate the \"Origin\" header on all incoming connections to prevent DNS rebinding attacks. Prior to the v0.25.0 release, users had no way to validate the origin's host. In v0.25.0, a new \"--allowed-hosts\" flag was introduced alongside the existing \"--allowed-origins\" flag, enabling users to specify permitted hosts at server startup. Both flags default to \"*\", allowing users to implement strict access controls as needed without breaking existing setups. If either flag is set to \"*\", the server will output a startup warning about potential vulnerabilities.
