CVE-2021-24593
The Business Hours Indicator WordPress plugin before 2.3.5 does not sanitise or escape its 'Now closed message" setting when outputting it in the backend and frontend, leading to an Authenticated Stored Cross-Site Scripting issue
Does this matter?
Lower severity and a low EPSS score (0.62%). Track it; it rarely justifies an emergency change on its own.
