CVE-2026-10039: Frontend Admin WordPress Plugin SQL Injection Vulnerability

Technical summary

CVE-2026-10039 is a SQL injection vulnerability (CWE-89) in the Frontend Admin plugin for WordPress. The vulnerability stems from insufficient input escaping and lack of parameterized query preparation on the 'order' parameter. When an attacker supplies both a malicious 'order' value and a valid 'orderby' parameter in the same request, the unsanitized 'order' input is concatenated directly into the SQL query string, enabling SQL injection. The vulnerability requires authentication with administrator-level or higher privileges and can be exploited remotely without user interaction, though data extraction is the primary impact.

Business impact

While this vulnerability requires high-privilege access, it presents a risk to WordPress installations if administrator accounts are compromised or if a malicious actor gains administrative access through other means. Unauthorized database access could lead to exposure of sensitive site data, user credentials, or customer information stored in the WordPress database. The impact is primarily confidentiality-focused; the vulnerability does not enable data modification or system availability attacks. Organizations running Frontend Admin should treat this as a medium-priority issue that compounds the risk of compromised administrator accounts.

Affected systems

The Frontend Admin by DynamiApps plugin for WordPress is affected in all versions up to and including 3.28.28. Any WordPress installation using this plugin with that version or earlier is potentially vulnerable. The vulnerability requires active exploitation by an authenticated user with administrator-level access, so exposure is limited to sites where the attacker has already escalated privileges within WordPress.

Exploitability

Exploitation requires two key conditions: the attacker must have authenticated access with administrator privileges in WordPress, and must supply both a valid 'orderby' parameter and a malicious 'order' parameter in the same request to trigger the vulnerable code path. The barrier to exploitation is the requirement for high-privilege authentication; once an attacker possesses administrator credentials, the SQL injection itself is straightforward to execute. No public exploit code or active exploitation has been reported in the wild.

Remediation

Update the Frontend Admin plugin to a patched version released after 3.28.28. Verify the availability of a security update from DynamiApps and apply it as soon as testing permits. In the interim, apply principle of least privilege by auditing administrator account assignments and disabling unused administrative accounts. Monitor database access logs for unusual SQL queries originating from the plugin.

Patch guidance

Check DynamiApps' official plugin repository and security advisories for a version newer than 3.28.28 that addresses this vulnerability. Apply the update through WordPress's plugin management interface or manually if required. Test the update in a staging environment before production deployment to ensure compatibility with your site configuration. If no patch has been released, contact DynamiApps for a security update timeline.

Detection guidance

Monitor database query logs for unusual SQL patterns in requests that include both 'order' and 'orderby' parameters. Look for administrator-initiated requests containing SQL keywords (UNION, SELECT, OR, etc.) in the 'order' parameter value. Web application firewalls can be configured to detect and block payloads typical of SQL injection attempts. Additionally, audit administrator account activity for suspicious database queries or unusual data export patterns.

Why prioritize this

Although the CVSS score is 4.9 (Medium), this vulnerability should be prioritized based on your security posture regarding administrator account protection. If your WordPress administrators use strong, unique credentials and multi-factor authentication is enforced, risk is lower. However, if administrator accounts are shared, use weak passwords, or lack MFA protection, this vulnerability becomes higher-risk. The issue warrants swift patching in all cases because it provides a direct path to sensitive database extraction once an attacker has administrative access.

Risk score, explained

The CVSS 3.1 score of 4.9 reflects high confidentiality impact (C:H) offset by the requirement for high-privilege authentication (PR:H) and no impact on integrity or availability. The attack vector is network-based and requires no user interaction, but the prerequisite of administrator-level access significantly constrains the attack surface. Organizations with robust administrator credential management and monitoring may assess this as lower-risk than the base score suggests.
