CVE-2026-35143 · Severity: low · CVSS 3 · Published 2026-07-16

HCL DFXAnalytics, a data analytics platform, contains a security flaw where session cookies are not properly configured to prevent unauthorized cross-site requests. If a logged-in user visits a malicious website, an attacker could potentially perform actions on the user's behalf within the DFXAnalytics application. This risk is primarily present if the application lacks other standard defenses like anti-forgery tokens.

## Technical details

HCL DFXAnalytics fails to set the 'SameSite' attribute on session cookies generated during the authentication process. This omission allows the browser to send the session cookie during cross-site requests, creating a vulnerability to Cross-Site Request Forgery (CSRF). An attacker could exploit this by tricking an authenticated user into visiting a malicious site that triggers unauthorized requests to the DFXAnalytics application. The impact is mitigated if the application implements secondary defenses such as Anti-CSRF tokens. The vulnerability affects version 3.0 and below.

## Affected products
