CVE-2025-31920

Vulnerability

Analysis

The WP Guppy plugin for WordPress (versions through 4.3.3) contains an Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability [1]. The root cause is that user-supplied input is not properly sanitized before being used in SQL queries, allowing an attacker to inject arbitrary SQL commands.

Exploitation

No authentication is required to trigger the vulnerability, making it accessible to any visitor of a WordPress site running the affected plugin [1]. The attack surface is broad because the plugin is installed on thousands of websites, and this type of flaw is frequently targeted by automated mass-exploit campaigns that scan for vulnerable instances regardless of site size or popularity.

Impact

Successful exploitation enables a malicious actor to directly interact with the site's database [1]. This can lead to extraction of sensitive information (such as user credentials, personal data, or configuration details), as well as potential modification or deletion of data. The CVSS v3 base score is 8.5 (High), reflecting the serious confidentiality and integrity impact.

Mitigation

Users must update the WP Guppy plugin to a patched version immediately [1]. If immediate updating is not possible, administrators should contact their hosting provider or web developer for assistance. The vulnerability is expected to be actively exploited, so prompt action is critical.
