Security readout for executives and security teams

This is an old browser-specific cross-site scripting issue in HTML Purifier before 4.1.1, including deployments where products such as Mahara bundled it. If exposed, an attacker could get malicious script or HTML through content filtering for Internet Explorer users. Business impact depends on whether affected legacy code and IE clients still exist. Exposure is most likely in legacy web applications that still use HTML Purifier before 4.1.1, especially products bundling it, and where Internet Explorer or IE compatibility modes can render user-supplied HTML. Treat this as a legacy-risk cleanup item unless affected systems still process untrusted HTML for IE users. No active exploitation is cited, but vulnerable filtering in user-content applications can affect sessions, data integrity, and trust boundaries. Mitigation focus: Upgrade HTML Purifier to 4.1.1 or later where it is directly used.; Review Mahara release notes for branch-specific update guidance.; Identify products that bundle HTML Purifier and verify their patched versions..
