Authentication bypass via login-flow race condition
Published Jun 16, 2026 · Updated Jun 16, 2026
Authentication bypass in Rockwell Automation FactoryTalk Historian SE 11 allows remote attackers to obtain a valid session token. The login flow fails to synchronize shared authentication resources, so repeated invalid login requests can receive a token created during legitimate authentication. Exploitation requires concurrent legitimate authentication and grants the attacker that user's authenticated session context.
