Prior to version 2.5.7, the Bulk Link API endpoint (`POST /api/v2/bulk/links`) accepts URLs without any format validation, allowing an authenticated user to store a `javascript:` URI. The stored URI is later rendered verbatim as an `href` in Blade templates, and clicking it executes arbitrary JavaScript in the victim's browser — exfiltrating cookies and session tokens. Version 2.5.7 fixes the issue."
