Description
A flaw has been found in tobychui zoraxy up to 3.3.4. This impacts the function handleBasicAuth of the file mod/dynamicproxy/authProviders.go of the component Path Exception Matcher.

Upgrading to version 3.3.5-rc1 will fix this issue. Patch name: 37cd0f27b17cd15cfa4af409bfec943146f5fdfe. Upgrading the affected component is advised.
An authorization bypass vulnerability has been identified in Toby Chui Zoraxy versions through 3.3.4. The issue arises in the 'handleBasicAuth' function within 'mod/dynamicproxy/authProviders.go', specifically related to how path exception rules are matched. The vulnerability allows requests to bypass authentication by exploiting the path prefix matching logic, which fails to properly enforce boundaries. This issue can be exploited remotely, potentially exposing sensitive areas of an application that share a common path prefix with an intended exception.
Users can upgrade to Zoraxy version 3.3.5-rc1 to address this vulnerability. Instructions for downloading this version are available on the Zoraxy GitHub Releases page.
