Prior to 0.9.21, the fetch-apify-docs tool in src/tools/common/fetch_apify_docs.ts validates allowlisted documentation domains with String.startsWith() rather than URL hostname comparison, allowing attacker-controlled URLs such as `https://docs.apify.com.evil.com/` and `https://docs.apify.com@evil.com/` to pass the ALLOWED_DOC_DOMAINS check and return arbitrary fetched content to the LLM. This issue is fixed in version 0.9.21.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-20","CWE-183"],"references":["https://github.com/apify/apify-mcp-server/commit/e39bdee530da1db0b3b3d3713558b33c9608e629","https://github.com/apify/apify-mcp-server/pull/781","https://github.com/apify/apify-mcp-server/releases/tag/v0.9.21","https://github.com/apify/apify-mcp-server/security/advisories/GHSA-jwp7-wg77-3w9v","https://github.com/apify/apify-mcp-server/security/advisories/GHSA-jwp7-wg77-3w9v"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:08.599881581+00:00"},"epss":{"cve":"CVE-2026-46341","score":0.00234,"percentile":0.14217,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jwp7-wg77-3w9v","url":"https://osv.dev/vulnerability/GHSA-jwp7-wg77-3w9v","summary":"Apify Model Context Protocol (MCP) server: Domain Allowlist Bypass in fetch-apify-docs via String Prefix Matching","modified":"2026-09-10T03:51:06.238242148Z","packages":[{"ecosystem":"npm","name":"@apify/actors-mcp-server","purl":"pkg:npm/%40apify/actors-mcp-server","ranges":["<0.9.21"],"fixed":["0.9.21"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
