Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Application passwords could be used to bypass authentication unless explicitly disabled; fix added a filter but only when a setting is enabled, so default or misconfigured states remain risky.
Privilege Escalation: Admin user registration and role promotion were unguarded, allowing low-privilege users to escalate; fix added filters but must be verified on all user_register and role-update paths.
Reflected XSS: Payment instructions and script source were echoed without sanitization; fix added wp_kses_post and esc_html/esc_url, but any new output path could repeat the flaw.
