# NocoDB: forged X-Forwarded-For headers spoof logged IPs and evade rate limits

Link for people: https://infrastack.ai/live/CVE-2026-126268 (this .md is for agents)

NocoDB before 2026.08.0 trusts X-Forwarded-For headers unconditionally because Express trust proxy is always on. An unauthenticated attacker can write any source address into audit and request logs and bypass the per-address public API rate limiter.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:NocoDB affected range not listed fixed no fixed version listed
- npm:nocodb affected range not listed fixed no fixed version listed

## How to check

- Check the installed NocoDB version; anything below `2026.08.0` is affected.
- Look for a reverse proxy in front of NocoDB that sets X-Forwarded-For; the sources do not say whether this changes exposure.

## Fix

- NocoDB: move to `2026.08.0` or later.

## Timeline

## Documents

- [advisory] Vendor advisory: github.com https://github.com/nocodb/nocodb/security/advisories/GHSA-2rm5-wf7w-8j57
- [advisory] Third-party advisory: www.vulncheck.com https://www.vulncheck.com/advisories/nocodb-before-2026.08.0-ip-address-spoofing-via-unconditional-proxy-trust

## From the sources

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.
