Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-100534 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-2026-100534/ (Markdown: https://insights.sbomify.com/CVE-2026-100534/index.md)","id":"CVE-2026-100534","markdown":"https://insights.sbomify.com/CVE-2026-100534/index.md","name":"CVE-2026-100534","record":{"aliases":["GHSA-g24w-m94m-59qc","GHSA-gg3j-3f24-xwfp","MINI-7xgv-fpmp-36cw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenClaw server","requires_auth":"low_privilege","summary":"Attackers with webhook secrets can cancel unrelated sessions, causing denial of service and bypassing authorization controls in OpenClaw.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":2.3,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"OpenClaw versions before 2026.8.1 contain an authorization bypass vulnerability in webhook TaskFlow cancellation that allows attackers to cancel unrelated sessions.
