Upgrade laravel/framework to 5.5.10
illuminate/auth fixed: 5.5.10 
Upgrade illuminate/auth to 5.5.10
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for laravel/framework

How to Check if You Are Affected

To determine whether your application is affected by CVE-2017-14775, inspect your project dependencies for Laravel/framework:

inspect dependencies for laravel/framework

Analyze the terminal output to locate any version of Laravel/framework in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.5.10), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
