CVE-2025-52819 Overview
CVE-2025-52819 is a SQL Injection vulnerability affecting the Pakke Envíos WordPress plugin developed by pakkemx. The flaw stems from improper neutralization of special elements used in SQL commands, classified under [CWE-89]. All versions of Pakke Envíos through 1.0.2 are affected. An authenticated attacker with low privileges can inject arbitrary SQL statements through unsanitized input parameters. Successful exploitation enables data extraction from the WordPress database and can affect components beyond the vulnerable plugin due to scope change.
Critical Impact
Authenticated attackers can execute arbitrary SQL queries against the WordPress database, exposing sensitive information including user credentials, session tokens, and plugin configuration data.
Affected Products
- Pakke Envíos WordPress plugin versions through 1.0.2
- WordPress sites using the pakkemx Pakke shipping integration
- All deployments where the plugin is active and accessible to authenticated users

Technical Details for CVE-2025-52819
Vulnerability Analysis
The vulnerability is a classic SQL Injection flaw in the Pakke Envíos plugin. User-supplied input is concatenated directly into SQL queries without proper sanitization or parameterization. The CWE-89 classification confirms improper neutralization of special elements used in an SQL command. Attackers can submit crafted parameters containing SQL metacharacters such as single quotes, UNION SELECT statements, or stacked queries.
The EPSS score is 0.309% with a percentile of 22.338, indicating low predicted exploitation activity at this time. However, SQL injection vulnerabilities in WordPress plugins are routinely weaponized by automated scanning tools. The scope change (S:C) noted in the CVSS vector indicates that exploitation impacts resources beyond the vulnerable component, typically reflecting access to the broader WordPress database shared across plugins and core functionality.
Root Cause
The root cause is the failure to use prepared statements or the WordPress $wpdb->prepare() API when constructing SQL queries. Input parameters reach the database engine without escaping or type validation. This allows attacker-controlled data to alter query semantics.
Attack Vector
An attacker authenticates to the WordPress instance with any low-privileged account such as subscriber or contributor. The attacker then sends a crafted HTTP request to a plugin endpoint that processes the injectable parameter. The malicious payload modifies the underlying SQL query to return additional data, bypass authentication logic, or extract sensitive rows from wp_users, wp_usermeta, or other tables.

Detection Methods for CVE-2025-52819
Indicators of Compromise
- Unexpected SQL syntax such as UNION SELECT, SLEEP(, BENCHMARK(, or INFORMATION_SCHEMA references in web server access logs
- HTTP requests to Pakke Envíos plugin endpoints containing URL-encoded SQL metacharacters
- Database error messages returned in HTTP responses originating from plugin URLs
- Anomalous query response times suggesting time-based blind SQL injection
Detection Strategies
- Inspect WordPress access logs for requests targeting /wp-admin/admin-ajax.php and plugin-specific endpoints containing SQL keywords
- Enable MySQL general query log temporarily to capture suspicious queries originating from the WordPress process
- Deploy a Web Application Firewall (WAF) ruleset for SQL injection signatures targeting WordPress plugin parameters
- Correlate authenticated session activity with database query patterns to identify low-privileged accounts issuing administrative-style queries
Monitoring Recommendations
- Forward WordPress and web server logs to a centralized logging platform for retention and analysis
- Alert on spikes in 500-series HTTP responses from plugin endpoints, which often indicate failed injection attempts
- Monitor outbound database queries for unexpected SELECT operations against authentication tables
- Track new low-privileged user registrations followed by activity against plugin endpoints
How to Mitigate CVE-2025-52819
Immediate Actions Required
- Identify all WordPress sites running the Pakke Envíos plugin version 1.0.2 or earlier
- Deactivate the plugin until a patched version becomes available from the vendor
- Restrict authenticated access to the plugin by removing unnecessary user accounts and enforcing strong passwords
- Review WordPress audit logs for prior exploitation attempts and rotate credentials if compromise is suspected
Patch Information
At the time of publication, no fixed version has been disclosed in the NVD entry. Versions through 1.0.2 are confirmed vulnerable. Monitor the Patchstack Plugin Vulnerability Report and the official plugin repository for an updated release.
Workarounds
- Deploy a WAF rule that blocks SQL metacharacters in requests to Pakke Envíos plugin endpoints
- Apply virtual patching through Patchstack or equivalent WordPress security platforms
- Restrict database user privileges so the WordPress account cannot read sensitive system tables or write to schema objects
- Disable user registration and require administrator approval for new accounts to limit the authenticated attack surface
