CVE-2026-57385: Vitepos Lite SQL Injection Vulnerability

CVE-2026-57385 Overview

CVE-2026-57385 is a Blind SQL Injection vulnerability in the appsbd Vitepos (vitepos-lite) WordPress plugin. The flaw affects all versions from initial release through 3.4.2. The vulnerability is classified under CWE-89, Improper Neutralization of Special Elements used in an SQL Command.

An authenticated attacker with low privileges can inject arbitrary SQL statements through unsanitized input. The scope is changed, meaning the attack impacts components beyond the vulnerable plugin. Successful exploitation exposes confidential database contents and can degrade site availability.

Critical Impact
Authenticated attackers can extract sensitive WordPress database contents, including user credentials and session data, through blind SQL injection payloads.

Affected Products

appsbd Vitepos (vitepos-lite) WordPress plugin versions through 3.4.2
WordPress sites running the Vitepos point-of-sale plugin
Any deployment exposing the affected plugin endpoints to authenticated users

Technical Details for CVE-2026-57385

Vulnerability Analysis

The Vitepos plugin fails to properly neutralize special elements in user-supplied input before incorporating them into SQL queries. An authenticated attacker submits crafted parameters that alter the structure of backend queries executed against the WordPress database.

Because the injection is blind, the application does not return query results directly in HTTP responses. Attackers infer data by observing boolean conditions, time delays, or error-driven side effects. This technique enables full extraction of database contents given sufficient requests.

The vulnerability requires low-privilege authentication but no user interaction. Its scope-changed impact indicates that a successful attack affects security-relevant resources managed outside the plugin, such as the WordPress core database and other plugins sharing the schema.

Root Cause

The root cause is missing or insufficient input sanitization and parameterization. Vitepos concatenates user-controlled values directly into SQL statements rather than using prepared statements with the WordPress $wpdb->prepare() API. Any input reaching the vulnerable code path is interpreted as SQL syntax.

Attack Vector

The attack vector is network-based over HTTP or HTTPS. An attacker authenticates to WordPress with a low-privilege account, such as a subscriber or shop-manager role provisioned by the plugin. The attacker then submits SQL payloads through the affected plugin parameter.

Blind SQL injection typically uses conditional expressions such as AND SLEEP(5) or AND SUBSTRING(...) = 'a' to enumerate data one character at a time. Automated tooling such as sqlmap accelerates enumeration significantly.

Detection Methods for CVE-2026-57385

Indicators of Compromise

HTTP POST or GET requests to vitepos-lite plugin endpoints containing SQL syntax such as UNION, SLEEP(, BENCHMARK(, or SUBSTRING(
Repeated authenticated requests from a single session with incremental parameter mutations characteristic of blind extraction
Unusually high database query latency correlated with plugin request timestamps
Web server access logs showing URL-encoded SQL operators such as %27, %20OR%20, or %20AND%20

Detection Strategies

Deploy a web application firewall rule set with signatures for SQL injection targeting WordPress plugin routes
Enable MySQL general query logging temporarily and inspect queries originating from the Vitepos plugin for unusual structure
Monitor WordPress authentication logs for low-privilege accounts issuing large volumes of plugin requests

Monitoring Recommendations

Alert on request bursts exceeding a baseline threshold against /wp-admin/admin-ajax.php or plugin-specific endpoints
Correlate slow-query logs with authenticated session identifiers to surface time-based blind injection
Track creation of new low-privilege WordPress accounts followed by immediate plugin interaction

How to Mitigate CVE-2026-57385

Immediate Actions Required

Update the Vitepos plugin to a version later than 3.4.2 once the vendor releases a fix
Deactivate and remove vitepos-lite from any WordPress installation where an update is not yet available
Rotate WordPress database credentials and administrator passwords if exploitation is suspected
Audit the wp_users and wp_usermeta tables for unauthorized account creation or privilege changes

Patch Information

No fixed version is listed in the NVD entry at publication. Monitor the Patchstack Vulnerability Report and the plugin's WordPress.org listing for a patched release.

Workarounds

Restrict access to the plugin's endpoints by IP allowlist at the web server or WAF layer
Disable the plugin until a vendor patch is available and confirmed effective
Enforce least-privilege role assignments and remove low-privilege accounts that no longer require access
Deploy virtual patching rules on a WAF to block SQL metacharacters in plugin request parameters

bash

# Example nginx rule to block common SQL injection tokens on the plugin path
location ~* /wp-content/plugins/vitepos-lite/ {
    if ($args ~* "(union|sleep\(|benchmark\(|--|;)") {
        return 403;
    }
}
