Does this matter?

Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.

Description

An attacker who can inject data into the database, via limited back-office access or a previously existing vulnerability, can exploit unprotected variables in back-office templates.
