MEDIUM 4.6EPSS 0.82%

Does this matter?

Lower severity and a low EPSS score (0.82%). Track it; it rarely justifies an emergency change on its own.

Description

An issue was discovered in Open Ticket Request System (OTRS) 6.0.x through 6.0.7. A carefully constructed email could be used to inject and execute arbitrary stylesheet or JavaScript code in a logged in customer's browser in the context of the OTRS customer panel application.
