Published Jun 6, 2024 · Updated Aug 2, 2024

Stored XSS in the HCL Domino Catalog template in versions 11, 12, and 14 allows remote authenticated users to run script after a user click. The template retains attacker-supplied script in an editable catalog document and presents it for execution when an end user clicks the content. The script runs in the clicking user's browser context; exploitation requires catalog-document edit access and user interaction.
