Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-100556 in the wild and no public exploit code.\n\nAffected product: OpenClaw. 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-2026-100556/ (Markdown: https://insights.sbomify.com/CVE-2026-100556/index.md)","id":"CVE-2026-100556","markdown":"https://insights.sbomify.com/CVE-2026-100556/index.md","name":"CVE-2026-100556","record":{"aliases":["GHSA-8hvw-855c-9wjw","GHSA-mm7m-wcgh-8mfq","MINI-8p5p-8rr2-3567"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenClaw npm package","requires_auth":"low_privilege","summary":"A group member denied command access can reset the session to override provider and model settings, bypassing authorization controls.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"OpenClaw (npm package openclaw) versions \u003e= 2026.5.2 and \u003c 2026.8.1 contain an incorrect authorization vulnerability in WhatsApp group handling.
