MEDIUM 5.4EPSS 0.18%

Does this matter?

Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.

Description

IBM OpenPages 9.1 and 9.0 is vulnerable to HTML injection. A remotely authenticated attacker could inject malicious HTML code, which when viewed, would be executed in the victim's Web browser within the security context of the hosting site.
