Technical Analysis

The vector marks this flaw as requiring local or adjacent access, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Remediation

Update to version 1.12.22, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Form Maker by 10Web: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Form Maker by 10Web 1.12.22 closes this, and updating the plugin is the step that ends it.
