A critical security vulnerability in the Axiomthemes Veto WordPress plugin allows attackers to inject objects through deserialization. The National Vulnerability Database (NVD) assigned CVE-2026-93927 a CVSS score of 9.8, marking it as CRITICAL. This flaw impacts all versions of the Veto plugin up to and including version 1.6.0.

What is the technical nature of the flaw?

The vulnerability stems from the improper handling of untrusted data during the deserialization process. According to the NVD record, this weakness is classified under CWE-502, which covers the deserialization of untrusted data. This specific issue enables object injection, allowing an attacker to manipulate how data is reconstructed within the application.

Which software versions are at risk?

The NVD specifies that the Axiomthemes Veto plugin is affected from its initial release through version 1.6.0. Any WordPress site running these versions of the Veto plugin is potentially vulnerable to exploitation. The record does not indicate that later versions have patched this specific issue, nor does it confirm if a fix is available.

How severe is the potential impact?

With a CVSS score of 9.8, the NVD rates the severity of CVE-2026-93927 as CRITICAL. This high score indicates that exploitation is likely easy and could result in significant compromise of the affected system. Object injection attacks often lead to remote code execution, though the source material specifically highlights the object injection capability as the primary vector.
