OAuthRequestFilter Logic Error Allows Unauthorized Access

Publication date: 2026-06-12

Last updated on: 2026-06-12

Assigner: Apache Software Foundation

Description
A logic error in OAuthRequestFilter rejects legitimate requests originating from the bound IP address, while blindly allowing requests from any other IP address. Enabling this security feature inadvertently creates an inverse security check. Users are recommended to upgrade to versions 4.2.2 or 4.1.7, which fixes this issue.

Executive Summary

This vulnerability is a logic error in Apache CXF's OAuthRequestFilter component. It causes legitimate requests originating from the bound IP address to be rejected, while requests from any other IP address are allowed. This behavior inverts the intended security check, effectively allowing unauthorized access by bypassing the IP binding security control.

Impact Analysis

The vulnerability can impact you by allowing unauthorized access to your system. Because the security check is inverted, attackers from any IP address other than the bound one can bypass IP binding restrictions, potentially gaining access to protected resources or services.

Mitigation Strategies

To mitigate this vulnerability, users are advised to upgrade Apache CXF to versions 4.2.2 or 4.1.7, which contain the fix for the logic error in OAuthRequestFilter.
