Source: CVE Database V5
Vendor/Project: pr-gateway
Product: Blog2Social: Social Media Auto Post & Scheduler

Description

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.

Technical Analysis

CVE-2025-5673 is a SQL Injection vulnerability identified in the WordPress plugin 'Blog2Social: Social Media Auto Post & Scheduler' developed by pr-gateway. This vulnerability affects all plugin versions up to and including 8.4.4. The root cause is improper neutralization of special elements in the SQL command, specifically via the 'prgSortPostType' parameter. This parameter is insufficiently escaped and the SQL queries are not properly prepared, allowing an authenticated attacker with at least Subscriber-level privileges to inject additional SQL commands. Exploitation does not require user interaction and can be performed remotely over the network. The vulnerability allows attackers to append arbitrary SQL queries to existing ones, potentially enabling extraction of sensitive database information. The CVSS v3.1 score is 6.5 (medium severity), reflecting high confidentiality impact but no impact on integrity or availability. The attack vector is network-based with low attack complexity and requires privileges but no UI interaction. No known exploits are currently reported in the wild. The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). Given the widespread use of WordPress and the popularity of Blog2Social for automating social media posts, this vulnerability poses a significant risk to websites using this plugin, especially those with multiple user roles where subscribers or similar low-privilege users exist. Successful exploitation could lead to unauthorized disclosure of sensitive data stored in the WordPress database, such as user credentials, personal information, or business data. The lack of integrity and availability impact means the attack is primarily focused on data confidentiality breaches rather than system disruption or data manipulation. No patch links are currently available, indicating that mitigation may require manual intervention or plugin updates once released.

Potential Impact

For European organizations, the impact of CVE-2025-5673 can be considerable, especially for those relying on WordPress sites with the Blog2Social plugin installed. Sensitive data exposure could lead to privacy violations under GDPR, resulting in regulatory fines and reputational damage. Organizations in sectors such as media, marketing, e-commerce, and public services that use this plugin for social media automation may face data leakage risks. Attackers exploiting this vulnerability could access user data, internal communications, or business intelligence stored in the database. Although the attack requires authenticated access at Subscriber level, many WordPress sites allow user registrations or have multiple user roles, increasing the attack surface. The vulnerability does not allow data modification or denial of service, but confidentiality breaches alone can have severe consequences, including intellectual property theft and loss of customer trust. Additionally, the presence of this vulnerability could be leveraged as a foothold for further attacks within the network. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as exploit code may emerge rapidly after public disclosure.

Mitigation Recommendations

Immediately audit WordPress installations to identify the presence of the Blog2Social plugin and confirm the version in use. Restrict user registration and minimize the number of users with Subscriber-level or higher privileges to reduce potential attackers. Implement Web Application Firewall (WAF) rules specifically targeting SQL injection patterns on the 'prgSortPostType' parameter to block malicious payloads. Monitor database query logs for unusual or unexpected SQL commands that could indicate exploitation attempts. Until an official patch is released, consider disabling or uninstalling the Blog2Social plugin if it is not critical to operations. Apply the principle of least privilege for all WordPress users and enforce strong authentication mechanisms to limit unauthorized access. Regularly back up WordPress databases and files to enable recovery in case of compromise. Stay updated with vendor announcements for patches or updates addressing this vulnerability and apply them promptly once available. Conduct security awareness training for administrators and users about the risks of SQL injection and the importance of cautious user role assignments.
