Overview

A critical Code Injection vulnerability (CVE-2026-32525) has been identified in the JetFormBuilder WordPress plugin by Jetmonsters. Published on March 25, 2026, this vulnerability carries a CVSS score of 9.9, indicating severe potential impact. Successful exploitation allows an attacker to inject and execute arbitrary code within the context of the vulnerable application.

Description

CVE-2026-32525 is an Improper Control of Generation of Code (Code Injection) vulnerability with a CVSS score of 9.9, affecting JetFormBuilder versions from n/a through 3.5.6.1. The JetFormBuilder plugin fails to adequately sanitize or validate user-supplied input before incorporating it into dynamically generated code. This allows an attacker to introduce malicious code segments that the application then executes. The high CVSS score indicates that the vulnerability is exploitable remotely with no prior authentication required (AV:N, PR:N), with low attack complexity and no user interaction needed. The exact vulnerable function or injection point was not specified in the advisory; however, the nature of the flaw suggests the exploit path involves crafting specially formed input that manipulates the plugin's code generation logic.

Impact

Successful exploitation of this vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the web server hosting the WordPress site, potentially leading to complete compromise of the site, server, and any connected systems.

Solution

Users are strongly advised to update JetFormBuilder to a version beyond 3.5.6.1 as soon as a patched release is available. As an interim measure, disable the plugin if it is not critical to operations. Apply WAF virtual patching rules and monitor for any anomalous activity on affected WordPress installations.
