How to Fix CVE-2026-35410

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

directus fixed: 11.16.1 
npm install directus@11.16.1
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 directus

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-35410, inspect your project dependencies using npm:

npm ls directus

Analyze the terminal output to locate any version of Directus in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 11.16.1), your application is affected.

Note: The npm ls directus 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Directus, 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

### Summary An open redirect vulnerability exists in the login redirection logic. The `isLoginRedirectAllowed` function fails to correctly identify certain malformed URLs as external, allowing attackers to bypass redirect allow-list validation and redirect users to arbitrary external domains upon successful authentication. ### Details A parser differential exists between the server-side URL validation logic and how modern browsers interpret URL path segments containing backslashes. Specifically, certain URL patterns are incorrectly classified as safe relative paths by the server, but are normalized by browsers into external domain references. This is particularly impactful in SSO authentication flows (e.g., OAuth2 providers), where an attacker can craft a login URL that redirects the victim to an attacker-controlled site immediately after successful authentication, without any visible indication during the login process. ### Impact - **Phishing:** Users may be silently redirected to attacker-controlled sites impersonating legitimate services after authenticating. - **Credential/token theft:** The redirect can be chained to capture OAuth tokens or authorization codes. - **Trust erosion:** Users lose confidence in the application after being redirected to unexpected domains post-login.
