WordPress Theme Vulnerability Puts Soledad Users at Risk

CVSScvssV3_1: 8.1

The PenciDesign Soledad WordPress theme contains a deserialization of untrusted data vulnerability that could allow attackers to execute arbitrary code on impacted websites.

Deserialization vulnerabilities occur when user-supplied input containing serialized objects is deserialized without proper validation. This can enable attackers to execute code or functions by manipulating the serialized data before it is deserialized on the server.

In the case of Soledad, an attacker could craft a malicious serialized string and submit it to the theme. If deserialized, it could allow them to perform actions like adding admin users, modifying files, or installing malware on the vulnerable website.

All Soledad users are urged to update to version 8.4.2 or later, which fixes this issue. Administrators should always keep themes and plugins updated to the latest versions to protect against known vulnerabilities. It’s also recommended to review and restrict theme and plugin permissions to prevent unauthorized access.

Being vigilant about updating software and limiting access can help site owners bolster WordPress security and stay one step ahead of potential hackers exploiting known issues.
