Because `parse_expr()` internally calls `eval()` and does not explicitly block `__builtins__`, an attacker can embed arbitrary Python code (like `__import__('os').system()`) to execute OS commands with the privileges of the running process, including root access in containers.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-mw6r-2hvm-4rp2","publishedAt":"2026-08-25T15:26:43.000Z","cveId":"CVE-2026-55546","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":["other"],"issueType":"vulnerability","affectedPackages":["qwed-mcp@< 0.2.1 (fixed: 0.2.1)"],"affectedVendors":[],"affectedVendorsRaw":["qwed-mcp","SymPy"],"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":"2026-08-25T15:26:43.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null}}
