Multiple cross-site scripting (XSS) vulnerabilities in HTML Purifier before 4.1.0, when Internet Explorer is used, allow remote attackers to inject arbitrary web script or HTML via a crafted (1) background-image, (2) background, or (3) font-family Cascading Style Sheets (CSS) property, a different vulnerability than CVE-2010-2479.

Security readout for executives and security teams

This CVE affects older HTML Purifier versions before 4.1.0. If a site relied on it to clean untrusted HTML or CSS, Internet Explorer users could still receive attacker-controlled script or HTML through certain CSS properties. Business risk depends on whether the vulnerable library is still deployed in user-content workflows. Exposure is most likely in legacy PHP applications using HTML Purifier before 4.1.0 to sanitize user-submitted HTML or CSS that is later rendered to Internet Explorer users. Treat as a legacy exposure check rather than an emergency unless old HTML Purifier remains in production. Prioritize systems that display user-generated content, admin-submitted HTML, comments, profiles, or CMS content to authenticated users. Mitigation focus: Inventory applications using HTML Purifier and identify deployed versions.; Upgrade HTML Purifier to a non-vulnerable version per vendor guidance.; Review user-content rendering paths that allow HTML or CSS input..
