An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-35646 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- openclaw (npm): affected all versions; fixed in 2026.3.28\n- openclaw (npm): affected all versions; fixed in 2026.3.28\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-2026-35646/ (Markdown: https://insights.sbomify.com/CVE-2026-35646/index.md)","id":"CVE-2026-35646","markdown":"https://insights.sbomify.com/CVE-2026-35646/index.md","name":"CVE-2026-35646","record":{"aliases":["GHSA-mf5g-6r6f-ghhm","MINI-x98x-4f9m-r5v9"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenClaw server","requires_auth":"none","summary":"Attackers can bypass rate limits to brute-force weak webhook tokens, potentially gaining unauthorized access to OpenClaw services.","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":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-307","name":"Improper Restriction of Excessive Authentication Attempts"}],"description":"OpenClaw before 2026.3.25 contains a pre-authentication rate-limit bypass vulnerability in webhook token validation that allows attackers to brute-force weak webhook secrets.
