The rate limiter keys requests by `request.client.host`, which is derived from the `X-Forwarded-For` header when Uvicorn is launched with `--proxy-headers --forwarded-allow-ips *`. This configuration allows clients to control the value of `request.client.host`, effectively bypassing rate-limiting protections. This vulnerability leaves the affected endpoints open to unthrottled credential guessing attacks."}], "affected": [{"vendor": "zenml-io", "product": "zenml-io/zenml", "versions": [{"version": "unspecified", "lessThan": "0.95.0", "status": "affected", "versionType": "custom"}]}], "references": [{"url": "https://huntr.com/bounties/3cb8bf6a-ae55-4b38-8da3-601c666a210e"}, {"url": "https://github.com/zenml-io/zenml/commit/8a2214bdd63eb8200ce4719d82c6f0d935e922d1"}], "metrics": [{"cvssV3_0": {"version": "3.0", "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "NONE", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N", "baseScore": 6.5, "baseSeverity": "MEDIUM"}}], "problemTypes": [{"descriptions": [{"type": "CWE", "lang": "en", "description": "CWE-290 Authentication Bypass by Spoofing", "cweId": "CWE-290"}]}], "source": {"advisory": "3cb8bf6a-ae55-4b38-8da3-601c666a210e", "discovery": "EXTERNAL"}}}}
