CVE-2026-5118 — Divi Form Builder <= 5.1.2 - Unauthenticated Privilege Escalation via 'role'

The Divi Form Builder plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 5.1.2. This is due to the plugin accepting a user-controlled 'role' parameter from POST data during user registration without validating it against the form's configured default_user_role setting. This makes it possible for unauthenticated attackers to create administrator accounts by tampering with the role parameter during registration.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.5% (30-day exploitation probability)+7
  • Technical severity (critical)+10
  • Automatable exploitation (SSVC)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Divi Engine Divi Form Builder).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  4. Search available logs for exploit probes matching the vulnerability class (privilege escalation), errors and authentication anomalies.
