Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-100553 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-2026-100553/ (Markdown: https://insights.sbomify.com/CVE-2026-100553/index.md)","id":"CVE-2026-100553","markdown":"https://insights.sbomify.com/CVE-2026-100553/index.md","name":"CVE-2026-100553","record":{"aliases":["GHSA-9w3x-7vmw-xp4x","GHSA-h9jh-75j7-7hhx","MINI-hj4h-qg3v-v39h"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenClaw messaging platform","requires_auth":"low_privilege","summary":"Authenticated users can bypass cross-context policy restrictions to remove pins from other Feishu groups when specific security settings are disabled.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"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:N/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"OpenClaw versions \u003e= 2026.6.9 and \u003c 2026.8.1 do not declare the native chatId parameter as a delivery target in the Feishu unpin feature, so unpin requests can bypass the shared same-provider cross-context target check. When tools.message.crossContext.allowWithinProvider is disabled, an admitted (authenticated) sender can remove a pin from another Feishu group that the sender and the configured account are otherwise permitted to access, bypassing the intended cross-context message mutation policy. Feishu membership and group authorization still apply, and the demonstrated impact is limited to message mutation (pin removal).
