With the optional trulens and trulens-providers-litellm packages installed, an unauthenticated attacker can make the server send an outbound HTTP request to an arbitrary host carrying attacker-controlled headers.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-2wqp-q3c6-ccj5","publishedAt":"2026-10-23T22:07:26.000Z","cveId":"CVE-2026-115886","cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["supply_chain","denial_of_service"],"issueType":"vulnerability","affectedPackages":["mlflow@>= 3.12.0rc0, < 3.17.0 (fixed: 3.17.0)"],"affectedPackageNames":["mlflow"],"affectedPackageRefs":["pypi:mlflow"],"affectedVendors":[],"affectedVendorsRaw":["MLflow","TruLens","LiteLLM"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"epssCheckedAt":"2026-10-24T00:09:31.273Z","kevDateAdded":null,"advisoryAliases":["GHSA-2wqp-q3c6-ccj5"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-10-23T22:07:26.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":["AML.T0010"]}}
