CVE-2026-52712 Overview
CVE-2026-52712 is a SQL injection vulnerability in the WordPress Attendance Manager plugin affecting versions up to and including 0.6.2. The flaw allows an authenticated attacker with subscriber-level privileges to inject arbitrary SQL into backend database queries. Exploitation requires user interaction and yields a scope change, exposing sensitive database contents and impacting availability. The issue is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).
Critical Impact
A low-privileged subscriber account can extract sensitive WordPress database contents, including user records and password hashes, through crafted SQL payloads.
Affected Products
- WordPress Attendance Manager plugin versions <= 0.6.2
- WordPress sites running the plugin with open subscriber registration
- Any deployment exposing the vulnerable plugin endpoints to authenticated users

Technical Details for CVE-2026-52712
Vulnerability Analysis
The Attendance Manager plugin fails to neutralize special elements in user-supplied input before incorporating it into SQL statements. An authenticated attacker holding a WordPress subscriber role can submit crafted parameters to a plugin endpoint, causing the database engine to execute attacker-controlled SQL. Because the vulnerability changes the security scope, the attacker can reach data outside the plugin's intended boundary, including the broader WordPress wp_users and wp_usermeta tables. The flaw also enables partial availability impact through resource-intensive queries or destructive statements run against database content the plugin should not modify.
Root Cause
The root cause is missing parameterization in SQL queries built by the plugin. User-controlled input is concatenated directly into query strings rather than passed through $wpdb->prepare() with placeholders. The absence of input validation and escaping permits SQL metacharacters such as single quotes, UNION, and comment sequences to alter query structure.
Attack Vector
The attack vector is network-based and requires a valid low-privileged WordPress account combined with user interaction. The attacker authenticates as a subscriber, then triggers the vulnerable plugin endpoint with a payload that breaks out of the original query context. Successful exploitation typically uses UNION-based or error-based techniques to exfiltrate row data. Refer to the Patchstack advisory for vulnerability details. No public proof-of-concept exploit code has been released at the time of writing.
Detection Methods for CVE-2026-52712
Indicators of Compromise
- Web server access logs containing SQL keywords such as UNION SELECT, SLEEP(, INFORMATION_SCHEMA, or encoded variants in parameters sent to Attendance Manager endpoints
- Unexpected outbound queries against wp_users, wp_usermeta, or wp_options originating from the plugin's PHP context
- New or recently active subscriber accounts issuing repeated POST or GET requests to plugin URLs prior to data exfiltration
Detection Strategies
- Enable MySQL general query logging or slow query logging and alert on queries referencing authentication tables from the plugin's request path
- Deploy a Web Application Firewall (WAF) rule set that flags SQL injection patterns directed at /wp-admin/admin-ajax.php and Attendance Manager routes
- Correlate authenticated subscriber sessions with abnormal database response sizes or error rates
Monitoring Recommendations
- Audit WordPress user roles weekly and remove unused subscriber accounts created through open registration
- Forward WordPress, PHP, and database logs to a centralized analytics platform for retroactive hunting
- Monitor file integrity on plugin directories such as wp-content/plugins/attendance-manager/ to detect tampering
How to Mitigate CVE-2026-52712
Immediate Actions Required
- Disable the Attendance Manager plugin until a patched release is installed and verified
- Disable open WordPress registration or restrict it to vetted users to remove the subscriber prerequisite
- Rotate WordPress administrator passwords and invalidate active sessions if compromise is suspected
Patch Information
No fixed version is published in the NVD record at the time of writing. Site operators should consult the Patchstack advisory for vendor updates and apply the next plugin release that explicitly addresses CVE-2026-52712.
Workarounds
- Block external access to Attendance Manager endpoints at the WAF or reverse proxy layer
- Apply virtual patching rules that reject requests containing SQL metacharacters in plugin parameters
- Restrict database privileges of the WordPress MySQL user so it cannot read tables outside its required scope
# Example: temporarily deactivate the plugin via WP-CLI
wp plugin deactivate attendance-manager
# Example: restrict ModSecurity rule to log SQLi attempts on plugin paths
