CVE-2026-15103 getwpfunnels CVE debrief

Who should care

Authenticated attackers with the `wpf_manage_funnels` capability and above can exploit this vulnerability to elevate their privileges to administrator. This role is typically assigned to the Funnel Manager custom role created by the plugin, meaning this role is the minimum required to exploit the vulnerability.

Technical summary

The `update_settings()` REST callback fails to validate the `group_id` path parameter against an allowlist of permitted option names before passing it directly to `get_option()` and `update_option()`, allowing the built-in `wp_user_roles` option to be targeted. This makes it possible for authenticated attackers with the `wpf_manage_funnels` capability and above to elevate their privileges to administrator.
