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-2026-56259 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- crawl4ai (PyPI): affected all versions; fixed in 0.8.8\n- crawl4ai (PyPI): affected all versions; fixed in 0.8.8\n- crawl4ai (PyPI): affected all versions; fixed in 0.8.8\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-2026-56259/ (Markdown: https://insights.sbomify.com/CVE-2026-56259/index.md)","id":"CVE-2026-56259","markdown":"https://insights.sbomify.com/CVE-2026-56259/index.md","name":"CVE-2026-56259","record":{"aliases":["GHSA-f989-c77f-r2cq","GHSA-mw9f-q68p-364x","PYSEC-2026-3448"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Crawl4AI API server","requires_auth":"none","summary":"Attackers can exfiltrate LLM API keys and server secrets via unauthenticated endpoints, enabling authentication bypass and credential theft.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"crawl4ai","vendor":"kidocode"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Crawl4AI before 0.8.8 contains credential exfiltration vulnerabilities in the Docker API server that allow attackers to redirect LLM API calls to attacker-controlled endpoints and read arbitrary environment variables.
