CVE-2026-48211
Cross-Site Request Forgery in Import/Export Admin console
Description
An authenticated administrator can be induced to delete administrative Import/Export templates through a Cross-Site Request Forgery (CSRF) attack. The OTRS AdminImportExport::TemplateDelete action does not validate the request's ChallengeToken, allowing an unauthenticated remote attacker to craft a malicious request that is executed with the privileges of an active administrator session. This issue affects OTRS: * 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.7.X Please note that ((OTRS)) Community Edition 6.x and before are vulnerable. Products based on the ((OTRS)) Community Edition also very likely to be affected
