CVE-2025-32681 Overview
CVE-2025-32681 is a blind SQL injection vulnerability in the WP Guru Error Log Viewer plugin (error-log-viewer-wp) for WordPress. The flaw affects all plugin versions up to and including 1.0.5 and stems from improper neutralization of special elements used in SQL commands [CWE-89]. Authenticated attackers with low privileges can inject malicious SQL through unsanitized input, allowing them to extract sensitive database contents through inference-based queries. The scope is changed, meaning exploitation can affect resources beyond the vulnerable component itself. The vulnerability was published to the National Vulnerability Database on April 11, 2025.
Critical Impact
Authenticated attackers can execute arbitrary SQL queries against the WordPress database, exposing user credentials, session data, and other sensitive information stored in WordPress tables.
Affected Products
- WP Guru Error Log Viewer (error-log-viewer-wp) WordPress plugin
- All versions from initial release through 1.0.5
- WordPress installations with the vulnerable plugin enabled
Discovery Timeline

Technical Details for CVE-2025-32681
Vulnerability Analysis
The Error Log Viewer plugin fails to properly sanitize user-supplied input before incorporating it into SQL queries. This allows attackers to manipulate query logic and force the database to disclose information through observable side effects such as response timing or conditional output differences. Because the injection is blind, attackers cannot directly view query results in the HTTP response. Instead, they use techniques like time-based delays or boolean conditions to infer data character by character.
The changed scope indicates that successful exploitation impacts security boundaries beyond the plugin itself, reaching the underlying WordPress database and any data shared with other plugins or applications. Authenticated access is required, but the privilege threshold is low, meaning any user with subscriber-level or higher access could potentially exploit the flaw.
Root Cause
The root cause is the absence of parameterized queries or proper escaping when handling user-controlled input passed to database operations. The plugin likely concatenates input directly into SQL strings rather than using WordPress's $wpdb->prepare() function with placeholders. This pattern violates secure coding practices documented in the WordPress Plugin Developer Handbook.
Attack Vector
An authenticated attacker sends crafted HTTP requests containing SQL payloads to plugin endpoints that process user input. The injected SQL alters the query structure, allowing the attacker to issue subqueries, UNION operations, or conditional time delays. Refer to the Patchstack Vulnerability Report for additional technical context.
No public proof-of-concept exploit code is available for this vulnerability at the time of publication.
Detection Methods for CVE-2025-32681
Indicators of Compromise
- Unusual SQL syntax patterns such as SLEEP(), BENCHMARK(), UNION SELECT, or OR 1=1 appearing in WordPress access logs
- Repeated requests to Error Log Viewer plugin endpoints with varying parameter values indicating automated injection probing
- Slow database response times correlating with requests to plugin URLs, suggesting time-based blind injection
- Authentication events from low-privilege accounts immediately followed by plugin endpoint access
Detection Strategies
- Deploy a Web Application Firewall (WAF) with SQL injection signatures tuned for WordPress plugin endpoints
- Enable WordPress query logging or use database audit logging to capture anomalous query patterns
- Monitor for parameter tampering on requests to /wp-admin/admin.php and plugin AJAX handlers
- Correlate failed query errors in PHP error logs with specific authenticated session activity
Monitoring Recommendations
- Forward WordPress, PHP, and web server logs to a centralized analytics platform for query pattern analysis
- Alert on database errors containing syntax exceptions originating from plugin code paths
- Track baseline query volumes per authenticated session and flag deviations exceeding normal thresholds
- Review subscriber and contributor account activity for access to admin-only plugin functions
How to Mitigate CVE-2025-32681
Immediate Actions Required
- Deactivate and remove the Error Log Viewer plugin until a patched version is confirmed and installed
- Audit WordPress user accounts and remove unnecessary low-privilege accounts that could be leveraged for exploitation
- Rotate WordPress administrator credentials and database passwords if compromise is suspected
- Review database logs for evidence of data extraction during the exposure window
Patch Information
No patched version has been confirmed in the available CVE data. Administrators should monitor the Patchstack Vulnerability Report and the plugin's WordPress.org listing for updates beyond version 1.0.5.
Workarounds
- Restrict plugin access using WordPress role management to administrator accounts only
- Implement WAF rules blocking common SQL injection payloads targeting WordPress plugin URLs
- Replace the plugin with an alternative error log viewer maintained by a vetted developer
- Enforce least-privilege principles by disabling subscriber registration if it is not required
# Disable the vulnerable plugin via WP-CLI
wp plugin deactivate error-log-viewer-wp
wp plugin delete error-log-viewer-wp
# Verify removal
