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-2026-53820 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- openclaw (npm): affected all versions; fixed in 2026.5.12\n- openclaw (npm): affected all versions; fixed in 2026.5.12\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-2026-53820/ (Markdown: https://insights.sbomify.com/CVE-2026-53820/index.md)","id":"CVE-2026-53820","markdown":"https://insights.sbomify.com/CVE-2026-53820/index.md","name":"CVE-2026-53820","record":{"aliases":["GHSA-jxfq-h7pm-67ph","GHSA-qh2f-99mv-mrcf","MINI-g24w-7f5h-r52v","MINI-hv76-2hqf-48fh"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenClaw server","requires_auth":"low_privilege","summary":"Authenticated attackers can bypass exec denylist restrictions in OpenClaw's MCP session spawning, enabling unauthorized command execution.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"openclaw","vendor":"openclaw"}],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"OpenClaw before 2026.5.12 contains an exec denylist bypass vulnerability in the bundle MCP loopback session-spawn path that allows authenticated callers to bypass intended command restrictions.
