A security flaw has been identified in the Umami Analytics module for Drupal, known as a Cross-Site Scripting (XSS) vulnerability. This issue, tracked as CVE-2025-10931, could allow unauthorized script execution if not addressed. While rated as a low severity risk, it’s important for site administrators to understand the potential impact and apply the recommended updates promptly.
CVE Details
Product: Drupal Umami Analytics
Published Date: October 30, 2025
Severity: Low
Status: Analyzed
Affected Products
The vulnerability specifically impacts the Umami Analytics module for Drupal. Any versions of Umami Analytics from 0.0.0 up to, but not including, 1.0.1 are susceptible to this XSS vulnerability.
Current Status
The vulnerability has been thoroughly analyzed, and details, including mitigation steps and solutions, have been released. This means that developers and site administrators now have the information needed to protect their systems.
Severity Level
This Cross-Site Scripting vulnerability is classified as ‘Low’ severity. The primary reason for this rating is that exploiting this vulnerability requires an attacker to possess a specific administrative permission: “administer umami analytics.” This means that only users with elevated and typically trusted access to the Drupal site can potentially introduce malicious scripts. However, it’s crucial for administrators to understand that even low-severity issues can escalate if proper access controls are not in place or if an attacker gains unauthorized administrative access.
Possible Solutions
To safeguard your Drupal site from the CVE-2025-10931 vulnerability, follow these essential steps:
- Upgrade the Umami Analytics Module: The most direct solution is to update your Umami Analytics module to the latest secure version. Users should upgrade to Umami Analytics 1.0.1 or 2.0.0-beta3. These versions contain the necessary fixes to address the XSS vulnerability.
- Review User Permissions: It is highly recommended to audit and review which user roles have the “administer umami analytics” permission. Ensure that only highly trusted administrators have this permission. Limiting access reduces the attack surface, making it more difficult for an attacker to exploit the vulnerability even if they somehow compromise a lower-privileged account.
