An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-109239 in the wild and no public exploit code.\n\nAffected product: unclecode crawl4ai. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2026-109239/ (Markdown: https://insights.sbomify.com/CVE-2026-109239/index.md)","id":"CVE-2026-109239","markdown":"https://insights.sbomify.com/CVE-2026-109239/index.md","name":"CVE-2026-109239","record":{"aliases":["GHSA-f77g-77vp-r96v","GHSA-qm8q-557r-p5w7"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Crawl4AI web crawler","requires_auth":"none","summary":"Unauthenticated attackers can bypass egress controls to access internal services via blind SSRF in Crawl4AI's robots.txt parser.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Crawl4AI before 0.9.4 contains a blind server-side request forgery vulnerability in RobotsParser.can_fetch that lets unauthenticated attackers bypass Docker server egress controls.
