How to Fix CVE-2025-31138

To remediate this vulnerability, upgrade all affected Tarteaucitronjs dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

tarteaucitronjs fixed: 1.20.1 
npm install tarteaucitronjs@1.20.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls tarteaucitronjs

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-31138, inspect your project dependencies using npm:

npm ls tarteaucitronjs

Analyze the terminal output to locate any version of Tarteaucitronjs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.20.1), your application is affected.

Note: The npm ls tarteaucitronjs command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1021: Improper Restriction of Rendered UI Layers or Frames, where the web application does not restrict or incorrectly restricts frame objects or ui layers that belong to another application or domain. In Tarteaucitronjs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A vulnerability was identified in `tarteaucitron.js`, where user-controlled inputs for element dimensions (`width` and `height`) were not properly validated. This allowed an attacker with direct access to the site's source code or a CMS plugin to set values like `100%;height:100%;position:fixed;`, potentially covering the entire viewport and facilitating clickjacking attacks. ## Impact An attacker with high privileges could exploit this vulnerability to: - Overlay malicious UI elements on top of legitimate content, - Trick users into interacting with hidden elements (clickjacking), - Disrupt the intended functionality and accessibility of the website. ## Fix https://github.com/AmauriC/tarteaucitron.js/commit/25fcf828aaa55306ddc09cfbac9a6f8f126e2d07 The issue was resolved by enforcing strict validation and sanitization of user-provided CSS values to prevent unintended UI manipulation.
