Description Summary:
An unauthenticated PHP Object Injection vulnerability (CWE-502) affects the Integration for ActiveCampaign and various form plugins, potentially allowing remote code execution.
Executive Summary:
A critical deserialization vulnerability in the Integration for ActiveCampaign plugin allows unauthenticated attackers to execute arbitrary code on the host system.
Vulnerability Details
CVE-ID: CVE-2026-9691
Affected Software: Integration for ActiveCampaign and Contact Form 7, WPForms, Elementor, Ninja Forms
Affected Versions: Integration for ActiveCampaign and Contact Form 7, WPForms, Elementor, Ninja Forms <= 1.1.1 versions.
Vulnerability: The vulnerability is rooted in the insecure deserialization of untrusted data. An unauthenticated attacker can exploit this by sending a crafted payload to the affected plugin, bypassing security controls to execute malicious code.
Business Impact
With a CVSS score of 9.8, this vulnerability is critical. Successful exploitation allows an attacker to gain unauthorized control over the web server, which could lead to sensitive data exfiltration, modification of site content, or the installation of persistent backdoors.
Remediation Plan
Immediate Action: Upgrade the affected plugin to the latest version immediately to patch the insecure deserialization logic.
Proactive Monitoring: Review application and server access logs for anomalous traffic or unexpected execution patterns that deviate from normal plugin behavior.
Compensating Controls: Utilize a Web Application Firewall (WAF) to filter out common PHP object injection patterns and block malicious HTTP requests.
Exploitation Status
Public Exploit Available: false
Analyst Notes: As of Jun 15, 2026, there is no public information indicating active exploitation of this vulnerability. However, due to the nature of the flaw, the potential for exploitation is high.
Analyst Recommendation
This vulnerability presents a high risk of remote code execution. Organizations utilizing these integration plugins must prioritize patching, as unauthenticated RCE vulnerabilities are frequently targeted by automated exploit campaigns.
