Versions prior to 8.0.0.2 are vulnerable to stored cross-site scripting (XSS) via unescaped `portal_login_username` in the portal credential print view. A patient portal user can set their login username to an XSS payload, which then executes in a clinic staff member's browser when they open the \"Create Portal Login\" page for that patient. This crosses from the patient session context into the staff/admin session context. Version 8.0.0.2 fixes the issue."}], "lastModified": "2026-03-19T21:17:11.540", "sourceIdentifier": "security-advisories@github.com"}
