This is due to insufficient input sanitization and output escaping. While `sanitize_text_field()` strips HTML tags on save, it does not encode double quotes. The backup titles are output in HTML attribute contexts without `esc_attr()`. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts via attribute injection that will execute whenever another administrator views the backup list page.","keep-backup-daily",null,"\u003C=2.1.2","2.1.3","medium",4.4,"CVSS:3.1\u002FAV:N\u002FAC:H\u002FPR:H\u002FUI:N\u002FS:C\u002FC:L\u002FI:L\u002FA:N","Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","2026-03-20 00:00:00","2026-03-20 23:25:11",[19],"https:\u002F\u002Fwww.wordfence.com\u002Fthreat-intel\u002Fvulnerabilities\u002Fid\u002F18a4fa4b-5c99-4347-8b34-e49f7e0972be?source=api-prod",1]
