Received Received - Intake
IP Spoofing via X-Forwarded-For Parsing in OpenClaw

Publication date: 2026-03-19

Last updated on: 2026-03-25

Assigner: VulnCheck

Description
OpenClaw versions prior to 2026.2.21 improperly parse the left-most X-Forwarded-For header value when requests originate from configured trusted proxies, allowing attackers to spoof client IP addresses. In proxy chains that append or preserve header values, attackers can inject malicious header content to influence security decisions including authentication rate-limiting and IP-based access controls.

Can you explain this vulnerability to me?

This vulnerability exists in OpenClaw versions prior to 2026.2.21 where the software improperly parses the left-most X-Forwarded-For header value when requests come from configured trusted proxies.

Attackers can exploit this by spoofing client IP addresses. In scenarios where proxy chains append or preserve header values, attackers may inject malicious header content to manipulate security decisions.

These manipulated headers can affect mechanisms such as authentication rate-limiting and IP-based access controls.


How can this vulnerability impact me? :

The vulnerability allows attackers to spoof client IP addresses, which can undermine security controls that rely on accurate IP information.

  • Attackers may bypass authentication rate-limiting protections.
  • IP-based access controls can be circumvented, potentially granting unauthorized access.

Overall, this can lead to increased risk of unauthorized access and abuse of the system.


How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
