CVE-2024-51434Public exploitNetwork attack vector

Cross-site scripting via plaintext parsing discrepancy

Published Nov 7, 2024 · Updated Nov 8, 2024

Cross-site scripting in Froala Editor 4.3.0 and earlier allows remote attackers to execute browser scripts through crafted HTML. The clean.html() sanitizer parses a crafted sequence inconsistently with the browser, allowing a following event-handler element to survive cleaning and execute when rendered. The demonstrated path requires Code View access and later rendering without externally supplied DOMPurify, limiting impact to the consuming application's browser context.
