CVE-2021-25022
The UpdraftPlus WordPress Backup Plugin WordPress plugin before 1.16.66 does not sanitise and escape the backup_timestamp and job_id parameter before outputting then back in admin pages, leading to Reflected Cross-Site Scripting issues
Does this matter?
Lower severity and a low EPSS score (1.12%). Track it; it rarely justifies an emergency change on its own.
