MantisBT is Vulnerable to XSS leading to account takeover via updating a user's font family preference
Any authenticated user can inject arbitrary HTML via updating their account's font family.
Impact
Cross-site scripting. The injected payload will be reflected in every MantisBT page.
Leveraging another vulnerability (CSP bypass, see GHSA-9c3j-xm6v-j7j3), the attacker could achieve account takeover.
