We have identified and fixed a cross-site scripting (XSS) vulnerability in the Confluence action that performs the export to PDF.
- An attacker might take advantage of the vulnerability to steal other users' session cookies or other credentials, by sending the credentials back to such an attacker's own web server.
- An attacker's text and script might be displayed to other people viewing the Confluence page. This is potentially damaging to your company's reputation.
This issue is reported in our security advisory on this page:
