CVE-2023-0607Public exploitNetwork attack vector

Stored script execution via unvalidated template selection

Published Feb 1, 2023 · Updated Mar 27, 2025

Stored cross-site scripting in ProjectSend before r1606 allows remote authenticated users to execute script through a crafted template selection. The administrative templates.php handler writes the activate_template query value to selected_clients_template without first requiring it to match an installed template location. Administrative access is required to change the setting, and the stored value causes attacker-controlled script to execute when the affected template output is viewed.
