Impact

This issue is a CWE‑502 – Deserialization of Untrusted Data vulnerability. The vulnerability in the uxper Nuss WordPress theme arises from deserialization of untrusted data, permitting PHP Object Injection. When the theme processes maliciously crafted serialized objects, the attacker can trigger the execution of arbitrary PHP code on the server, potentially compromising the entire WordPress site.

Affected Systems

uxper’s Nuss theme, versions from its first release through 1.3.3, is affected. Any WordPress installation that has this theme installed and at a version equal to or older than 1.3.3 falls within the risk scope.

Risk and Exploitability

The CVSS score of 8.8 classifies the issue as high severity, yet the EPSS score of less than 1% indicates a very low probability of exploitation at this time. The vulnerability is not listed in CISA KEV. The likely attack vector involves an attacker supplying or targeting serialized data that the theme processes during normal operation; if successful, object injection can lead to arbitrary code execution on the server.

OpenCVE Recommended Actions

  • Upgrade the Nuss theme to a version newer than 1.3.3, which includes the fix.

  • Perform a comprehensive scan of the WordPress installation for unexpected files or injected code that may have been introduced prior to patching, and remove any suspicious artifacts.
