CVE-2026-40735: CWE-502 Deserialization of Untrusted Data in Edge-Themes Reina
Unauthenticated PHP Object Injection in Reina <= 2.1 versions.
AI Analysis
Technical Summary
This vulnerability in Edge-Themes Reina (versions <= 2.1) is caused by unsafe deserialization of untrusted data, leading to PHP Object Injection. An unauthenticated attacker can exploit this to execute arbitrary code or disrupt service. The CVSS 3.1 vector (AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H) reflects network attack vector, high attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. No official patch or remediation information is currently available.
Potential Impact
Successful exploitation can lead to full compromise of the affected system, including arbitrary code execution and denial of service. Confidentiality, integrity, and availability of the system are all severely impacted. Since the vulnerability is exploitable without authentication, it poses a significant risk to exposed installations.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the affected application to trusted networks and monitor for suspicious activity related to deserialization. Avoid exposing the vulnerable versions publicly if possible.
