It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-23733 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- @lobehub/chat (npm): affected all versions up to 1.143.2; no fix listed\n- @lobehub/chat (npm): affected all versions up to 1.143.2; no fix listed\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-2026-23733/ (Markdown: https://insights.sbomify.com/CVE-2026-23733/index.md)","id":"CVE-2026-23733","markdown":"https://insights.sbomify.com/CVE-2026-23733/index.md","name":"CVE-2026-23733","record":{"aliases":["GHSA-4gpc-rhpj-9443"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Lobe Chat desktop app","requires_auth":"high_privilege","summary":"Attackers can execute arbitrary JavaScript via stored XSS in the Mermaid renderer, escalating to remote code execution through the Electron IPC bridge.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:R/S:C/C:H/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"LobeChat is an open source chat application platform.
