The system validates a hostname and locks the connection to a safe IP using a Node agent, but the REST path uses undici's fetch instead, which ignores the pinned agent and re-resolves DNS at connection time, allowing an attacker to point the initial validation to a public IP and then rebind to an internal IP to access cloud metadata, databases, or internal services.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-v42f-v8xc-j435","publishedAt":"2026-07-24T21:44:27.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":["@budibase/server@<= 3.38.1"],"affectedVendors":[],"affectedVendorsRaw":["Budibase"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":"2026-07-24T21:44:27.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":null,"llmSpecific":false,"classifierConfidence":0.75,"researchCategory":null,"atlasIds":null}}
