Project: Toc.js [1] Date: 2025-June-25 Security risk: *Moderately critical* 12 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2] Vulnerability: Cross-site Scripting

Affected versions: <3.2.1 CVE IDs: CVE-2025-48923 Description:  This module enables you to generate Table of content of your pages given a configuration.

The module doesn't sufficiently sanitise data attributes allowing persistent Cross-site Scripting (XSS) attacks.

This vulnerability is mitigated by the fact that an attacker must have a role with permission to enter HTML tags containing specific data attributes using other modules.

Solution:  Install the latest version:

* If you use the Toc JS module, upgrade to Toc Js 3.2.1 [3]
