CVE-2026-92082 describes a vulnerability in Payara Server where, by default, the system does not restrict the number of failed login attempts. This lack of limitation can enable brute force attacks against authentication mechanisms. Payara Server provides built-in automatic attack protection to mitigate this risk, and administrators can configure these protections as detailed in the official Payara security guide. The vulnerability affects multiple versions of Payara Server, including versions >=4.1.144 <4.1.2.191.57, >=5.20.0 <5.89.0, =5.2020.1, >=6.0.0 <6.40.0, =6.2023.1, >=7.0.0 <7.2.0, and >=7.2025.1 <7.2026.7.

The vulnerability allows an attacker to perform unlimited failed login attempts, potentially enabling brute force attacks to guess valid credentials. This could lead to unauthorized access if credentials are compromised. The impact is limited to authentication bypass attempts and does not indicate direct remote code execution or data disclosure. No known exploits are reported in the wild.

Administrators should enable and properly configure the built-in automatic attack protection features in Payara Server as described in the official security guide (https://docs.azul.com/payara/technical-documentation/payara-server-documentation/security-guide/administering-system-security.html). Since no explicit patch links are provided, it is recommended to check the vendor advisory for updates or fixed versions and apply them when available. Monitoring and limiting failed login attempts through configuration is the primary mitigation.
