CVE-2025-30787: EZ SQL Reports CSRF Vulnerability

CVE-2025-30787 Overview

CVE-2025-30787 is a Cross-Site Request Forgery (CSRF) vulnerability in the EZ SQL Reports Shortcode Widget and DB Backup WordPress plugin (elisqlreports) that enables attackers to inject Stored Cross-Site Scripting (XSS) payloads. This chained vulnerability allows malicious actors to trick authenticated administrators into performing unintended actions, resulting in persistent malicious script injection within the WordPress installation.

Critical Impact

Attackers can exploit this CSRF-to-XSS chain to hijack administrator sessions, deface websites, steal sensitive data, or establish persistent backdoors within vulnerable WordPress installations.

Affected Products

• EZ SQL Reports Shortcode Widget and DB Backup plugin versions through 5.25.08
• WordPress installations running vulnerable versions of the elisqlreports plugin

Technical Details for CVE-2025-30787

Vulnerability Analysis

This vulnerability represents a dangerous attack chain combining two distinct web application security weaknesses. The EZ SQL Reports plugin fails to implement proper CSRF token validation on sensitive administrative forms, allowing attackers to craft malicious requests that authenticated users can unknowingly execute. When combined with insufficient input sanitization, this CSRF weakness enables the injection and storage of malicious JavaScript code that executes in the context of any user viewing the affected content.

The vulnerability is particularly concerning because it affects a database reporting and backup plugin, which typically handles sensitive data and requires elevated privileges to operate. The stored nature of the XSS payload means that the malicious code persists in the database and executes automatically whenever victims access the compromised functionality.

Root Cause

The root cause of this vulnerability is twofold: first, the plugin lacks proper CSRF protection mechanisms such as nonce verification on form submissions that modify plugin settings or content. Second, user-supplied input is not adequately sanitized or escaped before being stored in the database and rendered in HTML output. This combination of missing security controls (CWE-352) creates an exploitable attack surface.

Attack Vector

The attack requires network access and user interaction. An attacker must craft a malicious webpage or email containing a hidden form or request that targets the vulnerable plugin endpoint. When an authenticated WordPress administrator visits the attacker-controlled page or clicks a malicious link, their browser automatically submits the forged request with their valid session cookies. The plugin processes this request as legitimate, storing the attacker's XSS payload. Subsequently, any user accessing the affected plugin page triggers the stored malicious script, which executes with the privileges of the victim's session.

The attack mechanism involves crafting a forged HTTP request that targets the plugin's vulnerable form handlers. When an administrator with an active WordPress session encounters this request, the browser automatically includes authentication cookies, causing the server to accept the malicious payload as a legitimate configuration update.

Detection Methods for CVE-2025-30787

Indicators of Compromise

• Unexpected or suspicious JavaScript code appearing in plugin settings or report configurations
• Unauthorized modifications to EZ SQL Reports plugin settings without administrator action
• Browser developer tools showing external script loads or suspicious DOM manipulations on plugin pages
• Server logs indicating POST requests to plugin endpoints from unfamiliar referrer URLs

Detection Strategies

• Review WordPress plugin settings for unauthorized changes, particularly in the EZ SQL Reports configuration
• Monitor web server access logs for unusual POST requests to elisqlreports plugin endpoints with external referrers
• Implement Web Application Firewall (WAF) rules to detect and block CSRF attack patterns targeting WordPress plugins
• Deploy client-side monitoring to detect XSS payload execution patterns

Monitoring Recommendations

• Enable and regularly audit WordPress activity logs for plugin configuration changes
• Configure alerts for administrative actions performed on the EZ SQL Reports plugin
• Implement Content Security Policy (CSP) headers to mitigate XSS payload execution
• Monitor outbound network connections from the WordPress server for data exfiltration attempts

How to Mitigate CVE-2025-30787

Immediate Actions Required

• Update the EZ SQL Reports Shortcode Widget and DB Backup plugin to a patched version when available
• Deactivate and remove the vulnerable plugin if it is not essential to site operations
• Review and audit existing plugin configurations for signs of unauthorized modifications or injected scripts
• Implement additional security controls such as WAF rules and CSP headers to reduce exploitation risk

Patch Information

As of the last CVE update, users should check the WordPress plugin repository and Patchstack WordPress Vulnerability Report for the latest patched version of the EZ SQL Reports plugin. Plugin versions through 5.25.08 remain vulnerable. Site administrators should update to a version higher than 5.25.08 once the vendor releases a security fix.

Workarounds

• Restrict access to the WordPress admin panel to trusted IP addresses only
• Implement additional authentication factors for WordPress administrator accounts
• Use a Web Application Firewall (WAF) with CSRF and XSS protection rules enabled
• Limit the number of users with administrative privileges to reduce the attack surface

# WordPress .htaccess example to restrict admin access by IP
<Files wp-login.php>
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from YOUR.TRUSTED.IP.ADDRESS
