The login fails with X-TC-CSRF-Token error when SentinelOne Agent is used

Symptoms

• The login with the TeamCity authentication fails with the authenticated POST request is made, but neither tc-csrf-token parameter nor X-TC-CSRF-Token header are provided error.
• The login with SSO may succeed initially, but any subsequent navigation in the UI will redirect to the login page again.
• Setting the teamcity.csrf.origin.check.enabled=logOnly internal property mitigates this issue.
• The TeamCity server startup command includes the -agentpath:C:\Program Files\SentinelOne\Sentinel Agent 25.1.3.334\SentinelJava64.dll=extendedCapabilities property.

Cause

There are known cases of the SentinelOne Agent usage leading to the CSRF issues.
