CVE-2026-65581: CWE-502 Deserialization of Untrusted Data in Axiomthemes AI ANN
CVE-2026-65581 is a critical vulnerability in Axiomthemes AI ANN versions up to and including 1.29.0. It involves unauthenticated PHP Object Injection due to deserialization of untrusted data (CWE-502). This flaw allows remote attackers to execute arbitrary code without any authentication. The vulnerability has a CVSS score of 9.8, indicating a high impact on confidentiality, integrity, and availability. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
This vulnerability is an unauthenticated PHP Object Injection in Axiomthemes AI ANN software versions <= 1.29.0. It arises from unsafe deserialization of untrusted data (CWE-502), which can lead to remote code execution. The CVSS v3.1 score is 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting that an attacker can exploit this vulnerability over the network without privileges or user interaction, resulting in full compromise of confidentiality, integrity, and availability. The vulnerability is publicly known and assigned CVE-2026-65581. No vendor advisory or patch links are currently provided, and the remediation level is unspecified.
Potential Impact
Successful exploitation allows remote unauthenticated attackers to execute arbitrary code on the affected system, leading to complete compromise of confidentiality, integrity, and availability of the AI ANN application and potentially the underlying host. This can result in data theft, system manipulation, and denial of service.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, consider restricting network access to the affected application and monitoring for suspicious activity related to deserialization attempts. Avoid exposing the vulnerable service to untrusted networks.
