CVE-2026-2279 in myLinksDump Plugin
Summary
by MITRE • 03/21/2026
The myLinksDump plugin for WordPress is vulnerable to SQL Injection via the 'sort_by' and 'sort_order' parameters in all versions up to, and including, 1.6 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 administrator-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 myLinksDump plugin for WordPress presents a critical SQL injection vulnerability identified as CVE-2026-2279, affecting all versions up to and including 1.6. This vulnerability stems from inadequate input sanitization and parameter handling within the plugin's database query execution logic. The flaw specifically manifests through the 'sort_by' and 'sort_order' parameters, which are directly incorporated into SQL queries without proper escaping or preparation mechanisms. Security researchers have classified this vulnerability under CWE-89, which represents improper neutralization of special elements used in an SQL command, making it a classic SQL injection vector that can be exploited by malicious actors with elevated privileges.
The technical exploitation of this vulnerability requires an authenticated attacker possessing administrator-level access or higher within the WordPress environment. Once authenticated, the attacker can manipulate the 'sort_by' and 'sort_order' parameters to inject malicious SQL code into existing database queries. This injection capability allows for the execution of arbitrary SQL commands that can extract sensitive data from the WordPress database, potentially including user credentials, configuration details, and other confidential information stored within the system. The vulnerability's impact is amplified by the fact that it operates within a privileged context, eliminating the need for additional attack vectors to achieve database access.
The operational implications of CVE-2026-2279 extend beyond simple data theft, as the vulnerability can be leveraged to perform more sophisticated attacks within the compromised WordPress environment. Attackers can use the SQL injection to escalate privileges, modify existing database entries, or even execute destructive operations such as data deletion or system corruption. The vulnerability aligns with ATT&CK technique T1078.004, which covers valid accounts used for persistence and privilege escalation, as the attack requires an existing administrative account but can potentially be used to maintain access or expand compromise. Additionally, this vulnerability fits within the broader context of T1566, representing a credential stuffing or privilege escalation attack vector that can be exploited by attackers who have already gained initial access to the system.
Organizations utilizing the myLinksDump plugin must implement immediate mitigations to address this vulnerability, including updating to the latest plugin version where the SQL injection has been properly patched. The fix should incorporate proper parameterized queries or prepared statements to prevent user-supplied input from being interpreted as SQL code. Security measures should also include monitoring for unusual database query patterns and implementing network-level protections such as web application firewalls to detect and block malicious SQL injection attempts. Regular security audits of WordPress plugins and themes should be conducted to identify similar vulnerabilities, with particular attention to parameter handling and input validation practices. The vulnerability serves as a reminder of the critical importance of proper input sanitization and parameter handling in web applications, particularly those that process user-supplied data within database contexts.
