CVE ID :CVE-2026-42344 Published : May 8, 2026, 11:16 p.m. | 24 minutes ago Description :FastGPT is an AI Agent building platform. In versions 4.14.11 and prior, FastGPT's isInternalAddress() function in packages/service/common/system/utils.ts is vulnerable to DNS rebinding (TOCTOU — Time-of-Check to Time-of-Use). The function resolves the hostname via dns.resolve4()/dns.resolve6() and checks resolved IPs against private ranges, but the actual HTTP request happens in a separate call with a new DNS resolution, allowing the DNS record to change between validation and fetch. At time of publication, there are no publicly available patches. Severity: 6.3 | MEDIUM Visit the link for more details, such as CVSS details, affected products, timeline, and more...
