CVE-2026-93000 in SPS-Suite Plugin
Summary
by MITRE • 09/28/2026
The SPS-Suite WordPress plugin through 1.4.0 does not sanitise the search query before using it in a SQL query when its static-page search feature is enabled, allowing unauthenticated attackers to perform SQL injection attacks.

The vulnerability identified within the SPS-Suite WordPress plugin prior to version 1.4.0 represents a critical security flaw rooted in insufficient input validation and sanitization mechanisms. Specifically, when the static-page search feature is activated, the application accepts user-supplied data from search queries without applying adequate filtering or escaping procedures before incorporating this data into database operations. This architectural oversight creates a direct pathway for unauthenticated attackers to manipulate backend SQL logic by injecting malicious code segments through standard web request parameters. The absence of proper sanitization means that any special characters or SQL syntax provided in the search field are passed directly to the underlying database management system, bypassing intended logical boundaries and allowing external entities to alter the structure of executed queries.
From a technical perspective, this flaw is classified under CWE-89, which denotes Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL Injection. The vulnerability arises because the plugin fails to distinguish between data input and executable code within the context of database interactions. By not utilizing parameterized queries or prepared statements, nor by strictly whitelisting allowed characters for search terms, the software treats user input as part of the command string itself. This allows an attacker to terminate the original query prematurely using SQL delimiters such as single quotes or semicolons and append new commands that can retrieve sensitive data from other tables, modify existing records, or potentially execute administrative functions depending on the privileges assigned to the database user account associated with the web application.
The operational impact of this vulnerability is severe due to its unauthenticated nature. Unlike vulnerabilities requiring a valid login session, an attacker does not need credentials to exploit this flaw, significantly lowering the barrier for entry and increasing the likelihood of automated scanning attacks targeting exposed WordPress installations. Successful exploitation can lead to unauthorized access to sensitive information stored within the database, including user profiles, configuration details, password hashes, and potentially other site-specific data managed by the plugin or associated themes. In worst-case scenarios where the database server is configured with excessive privileges, an attacker might leverage SQL injection techniques such as UNION-based extraction or error-based parsing to dump entire table structures or even achieve remote code execution through specific database features like LOAD_FILE or INTO OUTFILE commands, thereby compromising the integrity and confidentiality of the entire web infrastructure.
To mitigate this risk, immediate action is required by updating the SPS-Suite plugin to version 1.4.0 or later where these sanitization issues have been addressed. Developers should ensure that all user inputs are strictly validated against expected formats before processing and utilize prepared statements with parameterized queries for all database interactions to inherently prevent SQL injection attacks. Additionally, implementing a Web Application Firewall can provide an additional layer of defense by detecting and blocking malicious SQL patterns in incoming traffic. Regular security audits and code reviews focusing on input handling practices are essential to maintain robust application security posture and prevent similar vulnerabilities from being introduced during future development cycles.
