Session data theft via stored command name
Published Jan 28, 2026 · Updated Jan 28, 2026
Stored XSS in Flexense DiskPulse Enterprise and SyncBreeze Enterprise 10.4.18 allows remote authenticated users to steal session data. The /add_command?sid= handler stores the command_name parameter without sufficient validation before its value is rendered to another user. Exploitation requires application credentials and a second authenticated user to render the stored payload, exposing that user's session information.
