CVE-2024-28715Public exploitNetwork attack vector

Browser script execution via unsafe Markdown rendering

Published Mar 19, 2024 · Updated Nov 1, 2024

DOM-based XSS in DoraCMS 2.18 and earlier allows remote attackers to run script in a user's browser through crafted API documentation. The markdown0 function in markdown.jsx renders attacker-controlled OpenAPI description markup without neutralizing an image error handler. Exploitation requires a user to open the API documentation URL with its url parameter set to an attacker-hosted YAML file, after which script runs in the DoraCMS origin.
