Miggo AIRoot Cause Analysis

The vulnerability description explicitly implicates the URL checking infrastructure. The function isURLInSite in Plone's URLTool is responsible for validating URLs within the site. The advisory notes that crafted URLs with JavaScript payloads bypass sanitization, suggesting this function returns raw user input without escaping. The hotfix likely added proper sanitization here. References to 'URL checking infrastructure' and the XSS mechanism align with this function's role in processing URLs for validation.
