Vulnerability description

DayBreach CVE AI Research

CVE-2026-50628 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.

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.
