Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-100531 in the wild and no public exploit code.\n\nAffected product: openclaw slack. 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-2026-100531/ (Markdown: https://insights.sbomify.com/CVE-2026-100531/index.md)","id":"CVE-2026-100531","markdown":"https://insights.sbomify.com/CVE-2026-100531/index.md","name":"CVE-2026-100531","record":{"aliases":["GHSA-5xhr-95ww-q9w4","GHSA-v7hh-7676-rg67"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Slack integration library","requires_auth":"low_privilege","summary":"An authenticated user can download files from unauthorized Slack conversations due to a fail-open authorization check in the download handler.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"The @openclaw/slack npm package before 2026.8.1 contains an authorization flaw in its Slack download-file handler: when a file lacks the share metadata used to prove it belongs to the requested conversation, the conversation-authorization check fails open.
