CVE-2025-30989 Overview
CVE-2025-30989 is a SQL Injection vulnerability affecting the Renzo Tejada Libro de Reclamaciones y Quejas WordPress plugin. The flaw stems from improper neutralization of special elements used in an SQL command [CWE-89]. All versions up to and including 0.9 are affected. An authenticated attacker with high privileges can inject arbitrary SQL statements through vulnerable input handlers. The issue carries a CVSS 3.1 base score of 7.6 and a changed scope, meaning impact extends beyond the vulnerable component.
Critical Impact
Authenticated attackers can read sensitive database contents and partially disrupt site availability through crafted SQL payloads against the WordPress plugin.
Affected Products
- Renzo Tejada Libro de Reclamaciones y Quejas WordPress plugin
- Plugin versions from n/a through <= 0.9
- WordPress sites with the libro-de-reclamaciones-y-quejas plugin installed

Technical Details for CVE-2025-30989
Vulnerability Analysis
The plugin fails to properly neutralize special elements in user-controllable input before incorporating it into SQL statements. An attacker authenticated to a high-privilege role can submit crafted parameters that break out of the intended query context. The scope is marked as changed, indicating successful exploitation affects resources beyond the plugin itself, including the underlying WordPress database. Confidentiality impact is high, while integrity remains unaffected and availability is partially impacted. The vulnerability is reachable over the network without user interaction, making it exploitable through standard HTTP requests.
Root Cause
The root cause is the use of unsanitized input concatenated directly into SQL queries. The plugin does not enforce parameterized queries or use the WordPress $wpdb->prepare() API to safely bind user-supplied values. This pattern is the canonical example of [CWE-89] SQL Injection.
Attack Vector
Exploitation requires an authenticated session with elevated privileges within the WordPress instance. The attacker submits malicious SQL fragments through plugin-controlled parameters. The crafted input is incorporated into a backend SQL query, allowing extraction of arbitrary database rows or modification of query logic. Refer to the Patchstack SQL Injection Advisory for technical details published by the disclosing party.
Detection Methods for CVE-2025-30989
Indicators of Compromise
- Unexpected SQL syntax characters (single quotes, UNION, SELECT, --) in WordPress access logs targeting plugin endpoints.
- Unusual administrative or editor account activity correlated with HTTP requests against libro-de-reclamaciones-y-quejas plugin paths.
- Database query errors emitted in PHP error logs referencing the plugin's tables.
Detection Strategies
- Inspect web server logs for query strings containing SQL metacharacters directed at the affected plugin.
- Enable WordPress debug logging and review wpdb errors that may indicate injection attempts.
- Deploy a web application firewall (WAF) ruleset that flags SQL injection signatures against /wp-admin and plugin-specific endpoints.
Monitoring Recommendations
- Alert on high-privilege account logins followed by repeated plugin requests containing encoded SQL payloads.
- Track outbound database queries with anomalous structure or volume sourced from the WordPress host.
- Monitor file integrity for unexpected changes to WordPress core tables, options, or user records.
How to Mitigate CVE-2025-30989
Immediate Actions Required
- Disable or remove the libro-de-reclamaciones-y-quejas plugin until a fixed release is available.
- Restrict high-privilege WordPress accounts and enforce strong authentication, including multi-factor authentication.
- Audit existing administrator and editor accounts for unauthorized activity since the plugin was installed.
Patch Information
No fixed version has been published in the available references at the time of disclosure. Affected versions span n/a through <= 0.9. Site operators should monitor the Patchstack SQL Injection Advisory for vendor updates.
Workarounds
- Deploy a WAF rule that blocks SQL injection patterns targeting the plugin's request parameters.
- Limit access to the WordPress admin interface by IP allowlisting at the reverse proxy or firewall.
- Reduce the number of accounts assigned high-privilege WordPress roles to minimize the exploitable user pool.
# Configuration example: disable the vulnerable plugin via WP-CLI
wp plugin deactivate libro-de-reclamaciones-y-quejas
wp plugin delete libro-de-reclamaciones-y-quejas
