The vulnerability exploits four gaps in security validation: the `__self__` attribute (which retrieves the real Python builtins module) is not blocked, the `vars()` function is not restricted, attribute-based function calls bypass checks, and string concatenation bypasses string constant filters. An attacker can use these gaps to access the `__import__` function and run OS commands, completely defeating the sandbox protection.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-4mr5-g6f9-cfrh","publishedAt":"2026-05-29T22:30:13.000Z","cveId":"CVE-2026-47392","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":[],"issueType":"vulnerability","affectedPackages":["PraisonAI@<= 4.6.39 (fixed: 4.6.40)","praisonaiagents@<= 1.6.39 (fixed: 1.6.40)"],"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":"2026-05-29T22:30:13.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
