CVE-2023-44390 is a cross-site scripting (XSS) vulnerability affecting the HtmlSanitizer .NET library, specifically when configured to allow foreign content like 'svg' or 'math' elements. This medium-severity vulnerability (CVSS 6.1) allows an unauthenticated attacker to inject arbitrary HTML and JavaScript through user interaction, bypassing sanitization and potentially leading to client-side compromise. While the default configuration is not vulnerable, there is currently no evidence of active exploitation, public exploit code, or significant community discussion.
