The subprocess uses a blocklist of only 11 forbidden attributes, missing four key attributes (`__traceback__`, `tb_frame`, `f_back`, `f_builtins`) that attackers can chain together through exception handling to access the real Python builtins and execute arbitrary code, completely bypassing the sandbox.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-qf73-2hrx-xprp","publishedAt":"2026-04-08T19:17:28.000Z","cveId":"CVE-2026-39888","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":[],"issueType":"vulnerability","affectedPackages":["praisonaiagents@<= 1.5.114 (fixed: 1.5.115)"],"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":"2026-04-08T19:17:28.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
