Root Cause Analysis

The vulnerability stems from API endpoints returning error messages that include unescaped user input parameters. Key evidence includes:

The patch note explicitly states 'Don't return input params in error messages on the API'
The CVE description specifies XSS via parameter values in error messages
The blog post demonstrates XSS via manipulated file paths in /api/files endpoint errors
The vulnerability type (CWE-79) confirms improper input neutralization in web outputs While exact function names aren't provided in available resources, the pattern matches API error handling functions that incorporate user input into error responses without proper sanitization.
