description

OTRS SendSupportBundle is affected by a path traversal issue in OTRS 7.x, 8.x, 2023.x through 2025.x, and 2026.x before 2026.7.x; Community Edition 6.x and earlier are also affected. An authenticated administrator may cause deletion of files accessible to the OTRS process, subject to the permissions assigned to that process.

mitigation

Upgrade OTRS 2026.x to 2026.7.x or later. For affected releases without a documented fixed version, limit administrative access and restrict the OTRS process account so it cannot modify files outside its required directories.
