- It can lead to theft of user credentials or session tokens.
- It can enable unauthorized actions on behalf of users.
- It can damage the website's reputation and user trust.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
The vulnerability allows authenticated attackers with Contributor-level access to inject arbitrary web scripts via stored cross-site scripting (XSS). This can lead to unauthorized script execution when users access affected pages.
