## Technical details

The vulnerability is an authorization bypass (CWE-863) caused by improper input sanitization and insecure regular expression evaluation in the Protected Rule authorization check. The attack requires an authenticated user with a valid account assigned to the protected application, and affects deployments where administrators have explicitly configured Protected Rule policies. An attacker can craft malicious input to circumvent the authorization checks and gain access to protected resources. The issue is fixed in version 2026.9.1 and later; all earlier versions are vulnerable.
