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-2026-28474 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @openclaw/nextcloud-talk (npm): affected all versions; fixed in 2026.2.6\n- @openclaw/nextcloud-talk (npm): affected all versions; fixed in 2026.2.6\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-2026-28474/ (Markdown: https://insights.sbomify.com/CVE-2026-28474/index.md)","id":"CVE-2026-28474","markdown":"https://insights.sbomify.com/CVE-2026-28474/index.md","name":"CVE-2026-28474","record":{"aliases":["GHSA-r5h9-vjqc-hq3r"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Nextcloud Talk plugin","requires_auth":"none","summary":"Attackers can bypass allowlists in OpenClaw Nextcloud Talk by spoofing display names, gaining unauthorized access to restricted conversations.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"openclaw","vendor":"openclaw"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"OpenClaw's Nextcloud Talk plugin versions prior to 2026.2.6 accept equality matching on the mutable actor.name display name field for allowlist validation, allowing attackers to bypass DM and room allowlists.
