Can you explain this vulnerability to me?
This vulnerability is a stored cross-site scripting (XSS) issue in the pdfonline.foxit.com service, specifically within the Page Templates feature. An attacker can insert a malicious script as the template name, which is stored and later rendered into the web page's DOM without proper sanitization. This causes the malicious script to execute every time the affected PDF is loaded.
How can this vulnerability impact me? :
The vulnerability can lead to the execution of malicious scripts in the context of the user's browser when loading affected PDFs. This can result in unauthorized actions such as theft of sensitive information, session hijacking, or other malicious activities that compromise user security and privacy.
