OVERVIEW¶
Authenticated Stored Cross-Site Scripting (XSS).
DESCRIPTION¶
Due to improper validation, a user with the Publisher role can exploit a stored Cross-Site Scripting (XSS) vulnerability by uploading an SVG file to the Publisher portal.
IMPACT¶
By leveraging the XSS attack, a malicious actor can make the browser get redirected to an arbitrary website, make changes in the UI of the web page, retrieve information from the browser, or cause harm otherwise. However, since all the session-related sensitive cookies are set with the httpOnly flag and protected, session hijacking or similar attacks would not be possible.
