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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-269"],"references":["https://plugins.trac.wordpress.org/browser/pronamic-ideal/tags/10.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L144","https://plugins.trac.wordpress.org/browser/pronamic-ideal/tags/10.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L376","https://plugins.trac.wordpress.org/browser/pronamic-ideal/tags/10.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L379","https://plugins.trac.wordpress.org/browser/pronamic-ideal/tags/10.1.0/packages/wp-pay-extensions/gravityforms/src/Extension.php#L988","https://plugins.trac.wordpress.org/changeset/3630401/pronamic-ideal/trunk/packages/wp-pay-extensions/gravityforms/src/Extension.php"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:47:10.050265369+00:00"},"epss":{"cve":"CVE-2026-16635","score":0.00577,"percentile":0.47582,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
