Because parse_expr() calls eval() and Python injects __builtins__ by default, an attacker can embed expressions such as __import__('os').system(...) to run OS commands in the running process. The source reports confirmed root-level execution in a Docker container, requiring no authentication or special configuration.","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)"],"affectedPackageNames":["qwed-mcp"],"affectedPackageRefs":["pypi:qwed-mcp"],"affectedVendors":[],"affectedVendorsRaw":["qwed-mcp","SymPy"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00726,"epssCheckedAt":"2026-11-06T00:07:10.767Z","kevDateAdded":null,"advisoryAliases":["GHSA-mw6r-2hvm-4rp2"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-08-25T15:26:43.000Z","fixReleasedAt":"2026-06-13T14:15:24.902Z","daysToFix":-73,"fixCheckedAt":"2026-10-29T21:31:17.683Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"plugin","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"qwed-mcp","fixedVersion":"0.2.1","matchedVersion":"0.2.1","fixReleasedAt":"2026-06-13T14:15:24.902Z","daysToFix":-73,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:31:17.535Z"}]}}
