CVE-2024-51475Network attack vector

Browser-context HTML execution via unsanitized tags

Published May 16, 2025 · Updated Aug 26, 2025

HTML injection in IBM Content Navigator 3.0.11, 3.0.15, and 3.1.0 allows remote authenticated users to execute HTML in a victim's browser. IBM identifies basic XSS caused by improper neutralization of script-related HTML tags, but does not disclose the affected request, parameter, or code path. Exploitation requires low-privileged access and a victim to view the injected content; execution occurs in the hosting site's browser context, enabling content spoofing or browser-context data access.
