Unauthorized session actions via undisclosed script injection

Published Mar 18, 2026 · Updated Mar 18, 2026

Cross-site scripting in OpenText ZENworks Service Desk 25.2 and 25.3 allows remote authenticated users to execute JavaScript. OpenText has not disclosed the affected input, page, or output-encoding operation that permits attacker-controlled content to enter generated HTML. Exploitation requires an authenticated attacker and passive interaction from another user; successful execution enables actions with that user's privileges.
