CVE-2024-30115Network attack vector

Stored script execution via unsanitized HTML widget

Published Apr 30, 2025 · Updated May 1, 2025

Stored XSS in HCL Domino Leap 1.0 through 1.0.5 and 1.1 through 1.1.3 allows remote authenticated users to run script via HTML widgets. The deployed application's HTML widget applies an insufficient sanitization policy to author-supplied content, leaving executable client-side script in rendered output. An authenticated application author must supply the content, and execution requires a user to open the deployed application, exposing browser-accessible data and page content.
