The software checks if a hostname is safe by looking up its IP address and checking a blacklist, but then performs a separate DNS lookup when actually connecting. An attacker controlling DNS can return a public IP during the safety check and a private/internal IP during the actual connection, allowing them to access internal services like localhost or cloud metadata endpoints.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-gfq7-5x4g-3xhf","publishedAt":"2026-06-22T23:39:24.000Z","cveId":"CVE-2026-54353","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":[],"issueType":"vulnerability","affectedPackages":["@budibase/backend-core@< 3.39.9 (fixed: 3.39.9)"],"affectedVendors":["HuggingFace"],"affectedVendorsRaw":["Budibase"],"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":"2026-06-22T23:39:24.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"api","llmSpecific":false,"classifierConfidence":0.75,"researchCategory":null,"atlasIds":null}}
