In version 0.7.1 and prior, the U","summary":"UpTrain (a platform for testing and improving AI systems) in version 0.7.1 and earlier has a security flaw where it creates a default user with a predictable API key (a credential for accessing the system) and allows requests from any website due to an open CORS policy (cross-origin resource sharing, which controls whether websites can make requests to other domains). This means attackers could use any website to make authenticated requests to UpTrain and perform unauthorized actions as the default user.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-27621","publishedAt":"2026-08-17T16:16:46.290Z","cveId":"CVE-2025-27621","cweIds":["CWE-287"],"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":null,"affectedVendors":[],"affectedVendorsRaw":["UpTrain"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":null,"disclosureDate":"2026-08-17T16:16:46.290Z","capecIds":["CAPEC-114"],"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
