Stored script execution via unchecked customer profile update

Published Oct 30, 2023 · Updated Sep 9, 2024

Stored cross-site scripting in minCal 1.0.0 allows remote authenticated users to run script in another customer's browser. The customer-edit request accepts a user-controlled customer_id and stores customer_data[customer_name] without validating ownership or neutralizing HTML. An account with access to the Accounting profile editor can overwrite another customer's name, and the stored payload executes when the affected profile is viewed.
