CVE-2022-42449Network attack vector

Stored script execution via unsafe HTML uploads

Published Apr 30, 2025 · Updated May 1, 2025

Unrestricted HTML upload in HCL Domino Leap 1.0 through 1.0.5 allows remote authenticated users to run JavaScript in deployed apps. An unsafe default file-type filter accepts .html uploads, so deployed application content executes embedded JavaScript when another user opens it. An authenticated application author must upload and deploy the file, and a victim must interact with the deployed content; impact is limited to browser-accessible data and actions.
