# Publisher portal: uploaded SVG files can carry scripts to other users' browsers

The Publisher portal does not validate uploaded SVG files, so a user with the Publisher role can upload a crafted SVG that is stored and rendered. When a victim views it, the script can redirect their browser, alter the page, or read information from the browser, though httpOnly session cookies limit session hijacking.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

The Publisher portal fails to enforce proper validation on uploaded SVG files, allowing users with the Publisher role to inject malicious scripts. This weakness can be exploited by uploading a crafted SVG file, which is then stored and rendered by the application.

The security consequences include the ability for a malicious actor to redirect the victim's browser to an arbitrary website, modify the web page's UI, or retrieve information from the browser. However, the impact is mitigated as session-related sensitive cookies are protected with the httpOnly flag, preventing session hijacking.
