Any authenticated user can append `?bypass_filter=true` to requests, which skips access control checks (the rules that prevent regular users from using admin-restricted models), allowing them to use models they shouldn't have permission to access.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-v6qf-75pr-p96m","publishedAt":"2026-05-14T20:25:24.000Z","cveId":"CVE-2026-45365","cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":["open-webui@<= 0.8.10 (fixed: 0.8.11)"],"affectedVendors":[],"affectedVendorsRaw":["Open WebUI","Ollama","OpenAI"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0,"patchAvailable":true,"disclosureDate":"2026-05-14T20:25:24.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["integrity","confidentiality"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
