## Technical details

This is a stored cross-site scripting (XSS) vulnerability in the tarteaucitron.js library prior to version 1.13.1, arising from improper sanitization of HTML attributes. The vulnerable code reads element attributes without adequate filtering, allowing attackers to inject arbitrary JavaScript. An attacker must be able to control stored data (such as cookie consent configuration) that the library processes. The fix filters attributes to prevent XSS payload injection. Users should upgrade to v1.13.1 or later.
