CVE-2026-48211

Cross-Site Request Forgery in Import/Export Admin console

State: Published
Severity: 5.4 Medium
Published: Oct 12, 2026
Updated: Oct 15, 2026
Reserved: May 21, 2026

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
