This is due to the `update_settings()` REST callback failing 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 — which satisfies the route's loose `[\\w-]+` regex — to be targeted. This makes it possible for authenticated attackers with the `wpf_manage_funnels` capability and above to elevate their privileges to administrator by writing a crafted role definition containing arbitrary capabilities into the `wp_user_roles` option, thereby granting any WordPress role full site administrator access. The `wpf_manage_funnels` capability is typically assigned to the Funnel Manager custom role created by the plugin, meaning this role is the minimum required to exploit the vulnerability."}],"title":"WPFunnels <= 3.12.8 - Authenticated (Funnel Manager+) Privilege Escalation via 'group_id' Path Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/76ad6d21-f277-496f-aa6b-f9d5cb8a3801?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wpfunnels/tags/3.12.8/includes/core/rest-api/Controllers/class-settings-controller.php#L462"},{"url":"https://plugins.trac.wordpress.org/browser/wpfunnels/tags/3.12.8/includes/core/rest-api/Controllers/class-settings-controller.php#L66"},{"url":"https://plugins.trac.wordpress.org/browser/wpfunnels/tags/3.12.8/includes/core/rest-api/Controllers/class-settings-controller.php#L40"},{"url":"https://plugins.trac.wordpress.org/browser/wpfunnels/tags/3.12.8/includes/utils/class-wpfnl-functions.php#L1216"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3607181%40wpfunnels&new=3607181%40wpfunnels"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-269 Improper Privilege Management","cweId":"CWE-269","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH"}}],"credits":[{"lang":"en","type":"finder","value":"PRISM"}],"timeline":[{"time":"2026-07-08T17:13:14.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-07-15T20:13:20.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-16T13:28:22.085771Z","id":"CVE-2026-15103","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-16T15:11:22.220Z"}}]}}
