First, attackers could change where the server sent LLM (large language model) requests by controlling a `base_url` parameter, causing the server to send its API keys to an attacker's server. Second, attackers could read any environment variable (including passwords and secret keys) from the server by using the `env:` syntax in configuration, then combine this with the first flaw to steal those secrets. Since the Docker API required no authentication by default, anyone could exploit these flaws.","solution":"Upgrade to the patched version. The fix prevents request-supplied `base_url` values from being used (the server now only derives the endpoint from its configured provider name), and blocks `env:` resolution of environment variables with names containing SECRET, PASSWORD, PRIVATE, or prefixes like CRAWL4AI* and AWS_SECRET*, or specific names like SECRET_KEY, REDIS_PASSWORD, and TOKEN. As workarounds, enable authentication with `CRAWL4AI_API_TOKEN` or avoid storing sensitive secrets in the server environment alongside provider keys.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-f989-c77f-r2cq","publishedAt":"2026-06-16T21:00:31.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["data_extraction","pii_leakage"],"issueType":"vulnerability","affectedPackages":["crawl4ai@<= 0.8.7 (fixed: 0.8.8)"],"affectedVendors":["HuggingFace"],"affectedVendorsRaw":["Crawl4AI"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":true,"disclosureDate":"2026-06-16T21:00:31.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
