DescriptionGitHub Advisory

Horilla is a free and open source Human Resource Management System (HRMS). In version 1.4.0, the has_xss() function attempts to block XSS by matching input against a set of regex patterns. However, the regexes are incomplete and context-agnostic, making them easy to bypass. Attackers are able to redirect users to malicious domains, run external JavaScript, and steal CSRF tokens that can be used to craft CSRF attacks against admins. This issue has been fixed in version 1.5.0.

Public exploit code exists for this vulnerability, enabling attackers to redirect users to malicious sites, execute arbitrary JavaScript, and steal CSRF tokens for use in admin-targeted attacks. …
