This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate their own WordPress account to Administrator by tampering with the role field value in a form submission. Exploitation requires that an administrator has already configured a Pronamic Pay payment feed in Gravity Forms with the **Update User Role** option enabled and mapped to a form field; once that configuration is in place, no further preconditions exist to prevent an authenticated attacker from exploiting this vulnerability."}], "title": "Pronamic Pay <= 10.1.0 - Authenticated (Subscriber+) Privilege Escalation via Gravity Forms 'Update user role' Field", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/d42b8856-e5d0-4122-98a4-8c959832b271?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/pronamic-ideal/tags/10.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L379"}, {"url": "https://plugins.trac.wordpress.org/browser/pronamic-ideal/tags/10.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L376"}, {"url": "https://plugins.trac.wordpress.org/browser/pronamic-ideal/tags/10.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L988"}, {"url": "https://plugins.trac.wordpress.org/browser/pronamic-ideal/tags/10.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L144"}, {"url": "https://plugins.trac.wordpress.org/changeset?old_path=%2Fpronamic-ideal/tags/10.1.0&new_path=%2Fpronamic-ideal/tags/10.2.0"}, {"url": "https://plugins.trac.wordpress.org/changeset/3630401/pronamic-ideal/trunk/packages/wp-pay-extensions/gravityforms/src/Extension.php"}], "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": "Afan"}, {"lang": "en", "type": "finder", "value": "moonge"}], "timeline": [{"time": "2026-07-22T16:57:11.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-07-31T20:28:17.000Z", "lang": "en", "value": "Disclosed"}]}}}
