The vulnerability exists because the server listen call omits a host argument, defaulting to 0.0.0.0, and the /execute endpoint has no authentication checks before executing user-supplied code.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-22qr-rp27-j9wm","publishedAt":"2026-05-19T19:57:36.000Z","cveId":"CVE-2026-45805","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["@penpot/mcp@< 2.15.0 (fixed: 2.15.0)"],"affectedVendors":[],"affectedVendorsRaw":["Penpot"],"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":"2026-05-19T19:57:36.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":null,"llmSpecific":false,"classifierConfidence":0.75,"researchCategory":null,"atlasIds":null}}
