CVE-2026-22192 describes an authentication bypass vulnerability in Voltronic Power SNMP Web Pro version 1.1. The issue arises because the application relies on client-side localStorage values to enforce authentication state, which attackers can manipulate to bypass server-side access controls. This allows unauthenticated users to gain unauthorized access to privileged management functions. The vulnerability is classified under CWE-306 (Missing Authentication for Critical Function) and has a high CVSS 4.0 score of 8.8, indicating network exploitable, no privileges required, no user interaction, and high impact on integrity and availability.

Successful exploitation allows unauthenticated attackers to bypass authentication and access privileged management functions within the affected product. This can lead to unauthorized configuration changes or management actions, potentially compromising device integrity and availability. There are no reported exploits in the wild, but the vulnerability poses a significant risk given the high CVSS score and the critical nature of the affected functions.

No patch or official fix is currently available for this vulnerability. Since the product is not a cloud service, remediation depends on the vendor releasing an update. Until a fix is provided, users should restrict access to the management interface through network controls (e.g., firewall rules, VPN access) to trusted administrators only. Monitor vendor advisories for updates and apply patches promptly once available. Avoid relying on client-side authentication mechanisms for security.
