CVE-2022-2932Network attack vector

Script execution via special-character URL sanitization bypass

Published Aug 22, 2022 · Updated Aug 3, 2024

Reflected XSS in Bustle Digital Group Mobiledoc Kit before 0.14.2 allows remote attackers to run script through crafted link URLs. The bundled mobiledoc-dom-renderer 0.7.1 sanitizeHref() logic fails to reject URLs containing special characters before assigning them to anchor href attributes. A victim must render the crafted Mobiledoc content and interact with the malicious link, allowing script execution in the application's browser context.
