An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-42260 exists.\n\nAffected packages and fixed versions:\n- open-websearch (npm): affected all versions; fixed in 2.1.7\n- open-websearch (npm): affected all versions; fixed in 2.1.7\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-2026-42260/ (Markdown: https://insights.sbomify.com/CVE-2026-42260/index.md)","id":"CVE-2026-42260","markdown":"https://insights.sbomify.com/CVE-2026-42260/index.md","name":"CVE-2026-42260","record":{"aliases":["GHSA-v228-72c7-fx8j"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"MCP web search server","requires_auth":"none","summary":"An attacker can bypass SSRF protections in Open-WebSearch to access internal resources via bracketed IPv6 literals or non-resolving hostnames.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Open-WebSearch is a multi-engine MCP server, CLI, and local daemon for agent web search and content retrieval.
