Published Nov 13, 2026 CVSS 4.0 · 6.9 Medium EPSS n/a KEV · Not listed

Description

NocoDB before 2026.08.0 contains an IP address spoofing vulnerability that allows unauthenticated attackers to forge their recorded source IP by supplying X-Forwarded-For headers, because Express trust proxy is enabled unconditionally. Attackers can write arbitrary source addresses into audit and request logs to mislead investigations and evade the per-address public API rate limiter.
