CVE-2024-35239 is a medium-severity cross-site scripting (XSS) vulnerability affecting Umbraco Forms, an open-source .NET web forms solution. An authenticated user with "edit Forms" access can inject unsafe code into form components, potentially leading to client-side script execution. The attack requires user interaction (UI:R) and has low impact on confidentiality and integrity (C:L/I:L). While no active exploits, public exploit code, or significant community discussion have been observed, a mitigation involving configuring TitleAndDescription:AllowUnsafeHtmlRendering is available after upgrading to patched versions.
