      "title": "Path Traversal in SendSupportBundle allows File Deletion Outside the Intended Directory",
      "summary": "A path traversal vulnerability in the OTRS SendSupportBundle functionality allows an authenticated administrator to reference file paths outside the intended directory.\n\nThis may allow files accessible to the OTRS application process to be deleted. The vulnerability does not bypass operating system file permissions. On OTRS versions prior to OTRS 7, the effective permissions of the web server process are relevant. Starting with OTRS 7, access is limited by the permissions of the dedicated OTRS user. Files with overly permissive ownership or file system permissions may therefore also be affected.\n\nThe affected functionality may additionally attempt to include controlled files in a support bundle. However, support bundles are sent to a predefined OTRS support address, and direct disclosure of arbitrary files to the attacker has not been demonstrated.\n\nAn attacker therefore requires valid administrative access to exploit the vulnerable functionality. The primary demonstrated impact is the deletion of files outside the intended directory within the effective permissions of the OTRS application process.\n\nThis issue affects OTRS:\n\n  *  7.0.X\n  *  8.0.X\n  *  2023.X\n  *  2024.X\n  *  2025.X\n  *  2026.X before 2026.7.X\n\nPlease note that ((OTRS)) Community Edition 6.x and before are vulnerable. Products based on the ((OTRS)) Community Edition also very likely to be affected",
