It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-5833 exists.\n\nAffected packages and fixed versions:\n- mcp-server-taskwarrior (npm): affected all versions up to 1.0.1; no fix listed\n- mcp-server-taskwarrior (npm): affected all versions up to 1.0.1; 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-2026-5833/ (Markdown: https://insights.sbomify.com/CVE-2026-5833/index.md)","id":"CVE-2026-5833","markdown":"https://insights.sbomify.com/CVE-2026-5833/index.md","name":"CVE-2026-5833","record":{"aliases":["GHSA-95hg-3c55-xf9x"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Taskwarrior MCP server","requires_auth":"low_privilege","summary":"A local attacker can execute arbitrary commands via the server.setRequestHandler function in the mcp-server-taskwarrior library.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"},{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"A security vulnerability has been detected in awwaiid mcp-server-taskwarrior up to 1.0.1.
