The isInternalAddress() function in packages/service/common/system/utils.ts is vulnerable to DNS rebinding, a time-of-check to time-of-use flaw: it resolves the hostname with dns.resolve4()/dns.resolve6() and checks the IPs against private ranges, but the HTTP request runs as a separate call with a new DNS resolution, so the record can change between validation and fetch.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-42344","publishedAt":"2026-05-08T23:16:37.177Z","cveId":"CVE-2026-42344","cweIds":["CWE-367"],"cvssScore":"6.3","cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["FastGPT"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"FastGPT DNS rebinding in isInternalAddress() allows internal address bypass","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N","attackVector":"network","attackComplexity":"high","privilegesRequired":"low","userInteraction":"none","exploitMaturity":"unknown","epssScore":0.00148,"epssCheckedAt":"2026-11-08T12:09:01.373Z","kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-11-03T06:12:09.011Z","patchAvailable":null,"disclosureDate":"2026-05-08T23:16:37.177Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":["CAPEC-27"],"crossRefCount":0,"attackSophistication":"advanced","impactType":["confidentiality","integrity"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null,"fixes":[]}}
