Combined with no default authentication and no requirement for session validation, an attacker can trick a victim into visiting a malicious webpage that silently makes requests to the victim's local PraisonAI server to create rules that inject the attacker's instructions into all future agent runs on that machine.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-pvph-5j39-v8qc","publishedAt":"2026-08-25T15:18:20.000Z","cveId":"CVE-2026-55532","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["prompt_injection","supply_chain"],"issueType":"vulnerability","affectedPackages":["PraisonAI@< 4.6.58 (fixed: 4.6.58)"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["PraisonAI"],"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":"2026-08-25T15:18:20.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":["AML.T0010","AML.T0051"]}}
