CVE-2025-5673 in Blog2Social Plugin
Summary
by MITRE • 06/17/2025
The Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to SQL Injection via the ‘prgSortPostType’ parameter in all versions up to, and including, 8.4.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Blog2Social plugin for WordPress represents a widely used social media automation tool that enables users to schedule and publish content across multiple social platforms. This particular vulnerability affects versions up to and including 8.4.4, where the plugin fails to properly sanitize user input in the prgSortPostType parameter. The flaw exists within the plugin's database query handling mechanism, specifically in how it processes the prgSortPostType parameter that is passed through HTTP requests. The vulnerability stems from insufficient input validation and escaping techniques, allowing malicious actors to inject additional SQL commands into existing database queries.
The technical nature of this vulnerability can be classified as a classic SQL injection flaw, which falls under the CWE-89 category of improper neutralization of special elements used in an SQL command. The vulnerability operates through the plugin's lack of prepared statements or proper parameterization when handling the prgSortPostType parameter. When an authenticated user with subscriber-level privileges or higher submits a request containing malicious input in this parameter, the plugin processes the input without adequate sanitization, thereby allowing arbitrary SQL commands to be executed within the context of the database connection. This creates a pathway for attackers to manipulate the underlying database queries and potentially extract sensitive information.
The operational impact of this vulnerability is significant for WordPress installations using the affected plugin version. Attackers with subscriber-level access can leverage this vulnerability to perform unauthorized data extraction, including user credentials, personal information, and potentially administrative access details. The vulnerability's accessibility through low-privilege accounts makes it particularly dangerous as it can be exploited by users who do not typically have elevated permissions. This weakness enables attackers to bypass normal access controls and gain unauthorized insight into the WordPress database structure and content. The exploitation process allows for the execution of UNION-based SQL injection attacks, potentially leading to full database compromise and unauthorized access to sensitive information stored within the WordPress installation.
From a threat modeling perspective, this vulnerability aligns with ATT&CK technique T1213.002 for Data from Databases, where adversaries seek to extract sensitive information from database systems. The attack vector requires minimal privileges, making it an attractive target for attackers seeking to escalate their access within a WordPress environment. Organizations using this plugin should immediately consider implementing mitigations including input validation, parameterized queries, and regular security updates. The recommended approach involves applying the latest plugin version that addresses this vulnerability, implementing proper input sanitization mechanisms, and conducting thorough security audits of all installed plugins. Additionally, network segmentation and monitoring of database access patterns can help detect and prevent unauthorized SQL injection attempts, while maintaining proper access controls ensures that only authorized users can execute potentially dangerous operations within the system.
