Description Summary:
A critical PHP Object Injection vulnerability exists in the Axiomthemes AI ANN theme, allowing unauthenticated attackers to potentially execute arbitrary code.
Executive Summary:
A critical unauthenticated PHP Object Injection vulnerability in the Axiomthemes AI ANN theme enables remote attackers to compromise the integrity and availability of the affected system.
Vulnerability Details
CVE-ID: CVE-2026-65581
Affected Software: Axiomthemes AI ANN
Affected Versions: n/a through 1.29.0
Vulnerability: This flaw is a result of unsafe deserialization of untrusted data, specifically falling under CWE-502. An unauthenticated attacker can leverage this to inject malicious objects that lead to arbitrary code execution with the privileges of the web server.
Business Impact
The CVSS score of 9.8 underscores the severe potential for total system takeover. Exploitation of this vulnerability could lead to the theft of sensitive proprietary data, unauthorized modification of website content, and the potential for lateral movement into the wider internal network.
Remediation Plan
Immediate Action: Apply the latest security update released by Axiomthemes for the AI ANN theme to address the deserialization vulnerability.
Proactive Monitoring: Monitor web server logs for irregular query strings or POST requests that appear to contain serialized object signatures.
Compensating Controls: Utilize a Web Application Firewall (WAF) to inspect and block requests that attempt to exploit PHP deserialization vulnerabilities.
Exploitation Status
Public Exploit Available: No
Analyst Notes: As of Aug 6, 2026, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. The vulnerability is inherently exploitable by any remote user, making it a high priority for remediation.
Analyst Recommendation
Security teams must treat this vulnerability with high urgency given its critical CVSS rating. Ensure the AI ANN theme is updated to the latest version immediately to close the injection vector and protect against potential remote exploitation.
