Summary
tarteaucitron.js allows prototype pollution via custom text injection
Details

A vulnerability was identified in tarteaucitron.js, where the addOrUpdate function, used for applying custom texts, did not properly validate input. This allowed an attacker with direct access to the site's source code or a CMS plugin to manipulate JavaScript object prototypes, leading to potential security risks such as data corruption or unintended code execution.

Impact

An attacker with high privileges could exploit this vulnerability to: - Modify object prototypes, affecting core JavaScript behavior, - Cause application crashes or unexpected behavior, - Potentially introduce further security vulnerabilities depending on the application's architecture.

Fix https://github.com/AmauriC/tarteaucitron.js/commit/74c354c413ee3f82dff97a15a0a43942887c2b5b

The issue was resolved by ensuring that user-controlled inputs cannot modify JavaScript object prototypes.

Severity ?
5.5 (Medium)
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N
