An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-46341 exists.\n\nAffected packages and fixed versions:\n- @apify/actors-mcp-server (npm): affected all versions; fixed in 0.9.21\n- @apify/actors-mcp-server (npm): affected all versions; fixed in 0.9.21\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-2026-46341/ (Markdown: https://insights.sbomify.com/CVE-2026-46341/index.md)","id":"CVE-2026-46341","markdown":"https://insights.sbomify.com/CVE-2026-46341/index.md","name":"CVE-2026-46341","record":{"aliases":["GHSA-jwp7-wg77-3w9v"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Apify MCP server","requires_auth":"none","summary":"Attackers can bypass domain allowlists in the Apify MCP server to fetch arbitrary content, potentially exposing sensitive data to AI agents.","user_interaction":"required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-183","name":"Permissive List of Allowed Inputs"}],"description":"The Apify MCP server enables AI agents to extract data from websites using ready-made scrapers, crawlers, and automation tools available on the Apify Store.
