Hogwords Object Injection: Critical CVE-2026-93938 Threatens WordPress Sites on Version 1.2.7 or Earlier

The National Vulnerability Database assigned CVE-2026-93938 to a critical security flaw in the ThemeREX Group Hogwords plugin for WordPress. This vulnerability allows attackers to perform object injection by exploiting how the plugin handles data deserialization. Security teams must assess their environments immediately to determine if this software is installed.

The issue stems from improper handling of untrusted data within the plugin's codebase. According to the NVD record, the weakness is classified under CWE-502, which denotes deserialization of untrusted data. This specific flaw enables an attacker to inject malicious objects into the application, potentially leading to remote code execution or other severe impacts on the host system.

Context on the Vulnerability

The vulnerability has been rated as Critical with a CVSS score of 9.8. This high severity rating indicates that the flaw can be exploited remotely and requires no user interaction. The NVD description specifies that the issue allows for Object Injection through the deserialization process. Such flaws are dangerous because they can bypass standard security controls if the input is not properly validated before processing.

Who is Affected

The vulnerability affects all versions of the ThemeREX Group Hogwords plugin from its initial release through version 1.2.7. Any WordPress site running one of these affected versions is potentially exposed to exploitation. Site administrators should check their plugin list to see if Hogwords is active. If the installed version is 1.2.7 or lower, the site is vulnerable to this specific attack vector until a patch is applied.

Our take on the response

No official fix or updated version has been confirmed by the vendor yet. Security professionals should monitor official channels for a patched release. In the meantime, the risk remains high for any installation that has not been updated. Organizations should prioritize reviewing their plugin inventory to identify this specific software. Waiting for an official update is the safest course of action to avoid breaking site functionality.

Background: CVSS score

The Common Vulnerability Scoring System (CVSS) assigns a numerical score from 0.0 to 10.0 to software vulnerabilities. It calculates this number by weighing factors like attack complexity, required privileges, and impact on confidentiality, integrity, and availability. You use the score to compare the severity of different flaws, but you must adjust for your own context to prioritize fixes correctly.
