The request-body blocklist blocked vertex_credentials but missed this alias, letting the value reach the Vertex AI credential loader and read arbitrary local files sent to an attacker-controlled URL. Reading /proc/self/environ can expose LITELLM_MASTER_KEY and provider API keys, escalating to full proxy-admin control.","solution":"Upgrade to 1.95.0 or later. The fix adds the missing alias to the request-body blocklist, so no configuration change is needed once you upgrade. There is no reliable configuration workaround on affected versions.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-g5ff-637f-6q2m","publishedAt":"2026-10-27T15:32:36.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["litellm@< 1.95.0 (fixed: 1.95.0)"],"affectedPackageNames":["litellm"],"affectedPackageRefs":["pypi:litellm"],"affectedVendors":[],"affectedVendorsRaw":["LiteLLM","Vertex AI"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":["GHSA-g5ff-637f-6q2m"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-10-27T15:32:36.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
