Title

Apache CXF: OAuth2: Inverted IP Binding Check Defeats Security Control

Summary

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 or 3.6.12, which fixes this issue.

Summary

Apache CXF OAuth2 has Inverted IP Binding Check that Defeats Security Control

Details

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.

Severity

9.8 (Critical)

CVE-2026-50628

A flaw was found in the OAuthRequestFilter component of cxf. A logic error in this filter inadvertently creates an inverse security check when enabled. This issue causes legitimate requests from a bound IP address to be rejected, while requests from any other IP address are blindly allowed. This could lead to unauthorized access to resources.
