How to Fix CVE-2025-31476

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-2025-31476, 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. 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`, allowing a user with high privileges (access to the site's source code or a CMS plugin) to enter a URL containing an insecure scheme such as `javascript:alert()`. Before the fix, URL validation was insufficient, which could allow arbitrary JavaScript execution if a user clicked on a malicious link. ## Impact An attacker with high privileges could insert a link exploiting an insecure URL scheme, leading to: - Execution of arbitrary JavaScript code - Theft of sensitive data through phishing attacks - Modification of the user interface behavior ## Fix https://github.com/AmauriC/tarteaucitron.js/commit/2fa1e01023bce2e4b813200600bb1619d56ceb02 The issue was resolved by enforcing strict URL validation, ensuring that they start with `http://` or `https://` before being used.
