CVE-2026-43978
wger · wger
The wger fitness manager application suffers from an improper privilege management vulnerability that allows low-privileged users to perform unauthorized administrative actions.
Executive summary
An improper privilege management vulnerability in wger allows authenticated users to escalate privileges, potentially leading to a total compromise of the application.
Vulnerability
This is an improper privilege management vulnerability (CWE-269) where the application fails to correctly validate the roles or permissions of an authenticated user. This allows a standard, authenticated user to perform actions reserved for higher-privileged accounts.
Business impact
Successful exploitation results in unauthorized access to administrative functions, which could allow an attacker to modify user data, delete records, or alter application configuration. Given the CVSS score of 8.1, this represents a high risk to the confidentiality and integrity of the fitness data managed within the application.
Remediation
Immediate Action: Update to the latest version of wger (version 2.6 or later) as soon as it becomes available to remediate the privilege management flaw.
Proactive Monitoring: Review administrative audit logs for any actions performed by standard user accounts that would typically require elevated privileges.
Compensating Controls: Restrict access to the wger instance via VPN or IP whitelisting until the patch is applied, and verify that all user accounts are limited to the minimum necessary permissions.
Exploitation status
Public Exploit Available: Unknown
Analyst recommendation
This vulnerability highlights a critical failure in the application access control model. Administrators must monitor the vendor repository for the release of version 2.6 and apply the update immediately to prevent unauthorized privilege escalation and protect sensitive user information.
