CVE-2026-9700 Overview
CVE-2026-9700 is a time-based SQL Injection vulnerability in the Eventer plugin for WordPress. The flaw affects all versions up to and including 4.4.2. The vulnerability exists in the handling of the code parameter, which lacks sufficient escaping and prepared statement usage. Unauthenticated attackers can append additional SQL queries to existing database operations. Successful exploitation allows extraction of sensitive information from the WordPress database, including user credentials, session tokens, and configuration data.
Critical Impact
Unauthenticated remote attackers can extract sensitive database contents from WordPress sites running vulnerable Eventer plugin installations via time-based SQL injection through the code parameter.
Affected Products
- Eventer WordPress Event Manager Plugin — all versions up to and including 4.4.2
- WordPress sites with the Eventer plugin installed and activated
- Any hosting environment serving vulnerable Eventer plugin endpoints

Technical Details for CVE-2026-9700
Vulnerability Analysis
The vulnerability falls under [CWE-89] Improper Neutralization of Special Elements used in an SQL Command. The Eventer plugin passes the user-controlled code parameter directly into an SQL query without adequate escaping or parameterized statement binding. This enables attackers to break out of the intended query context and inject additional SQL clauses.
Because the injection is time-based, attackers infer data by triggering conditional delays. Queries containing constructs such as SLEEP() or BENCHMARK() return responses only after measurable delays. Attackers extract data character by character by observing response timing.
The vulnerability requires no authentication. Any unauthenticated visitor with network access to the vulnerable endpoint can send crafted requests. This aligns with the network attack vector and low complexity nature of the flaw.
Root Cause
The root cause is insufficient input sanitization combined with the absence of prepared statements in the SQL query construction path handling the code parameter. WordPress provides the $wpdb->prepare() API for parameterized queries, but the plugin concatenates user input directly into the query string.
Attack Vector
An unauthenticated attacker sends HTTP requests to the vulnerable endpoint with a malicious payload in the code parameter. The payload contains SQL syntax that closes the original query and appends attacker-controlled clauses. Time-based blind extraction techniques allow the attacker to enumerate database schemas, table contents, and administrative credentials without direct response data.
The vulnerability manifests through insufficient escaping on the code parameter. Refer to the Wordfence Vulnerability Report for technical details on the injection point and payload structure.
Detection Methods for CVE-2026-9700
Indicators of Compromise
- HTTP requests containing SQL keywords such as SLEEP, BENCHMARK, UNION SELECT, or WAITFOR in the code parameter
- Unusually long response times from Eventer plugin endpoints correlated with specific request patterns
- Repeated requests to the same endpoint with incrementing values or character-by-character variations
- Web server access logs showing high-volume automated requests from single source IPs targeting plugin URLs
Detection Strategies
- Deploy web application firewall (WAF) rules that inspect the code parameter for SQL metacharacters and time-based injection signatures
- Monitor database query logs for queries containing SLEEP() or BENCHMARK() functions originating from the WordPress user account
- Correlate HTTP request patterns against response time baselines to identify blind injection attempts
- Analyze WordPress access logs for anomalous request rates against Eventer plugin endpoints
Monitoring Recommendations
- Enable MySQL slow query logging with a threshold aligned to normal application behavior
- Configure alerts on WAF blocks targeting SQL injection signatures in WordPress plugin parameters
- Track baseline response times for plugin endpoints and alert on statistical deviations
- Review outbound network connections from the database server for unauthorized data exfiltration
How to Mitigate CVE-2026-9700
Immediate Actions Required
- Deactivate the Eventer plugin until a patched version is verified as installed
- Restrict access to Eventer plugin endpoints via WAF rules or IP allowlisting where feasible
- Audit the WordPress database for signs of unauthorized access, including new administrator accounts and modified user credentials
- Rotate all WordPress administrator passwords and any secrets stored in the database
Patch Information
At the time of publication, refer to the vendor listing at CodeCanyon Event Manager Plugin for update availability. Site administrators should upgrade to any version released after 4.4.2 that addresses the SQL injection flaw. Verify the changelog explicitly references the fix for CVE-2026-9700 before considering the deployment remediated.
Workarounds
- Deploy a WordPress-aware WAF with rules blocking SQL injection payloads targeting the code parameter
- Apply virtual patching at the reverse proxy layer to strip or reject requests containing SQL metacharacters in plugin parameters
- Restrict the WordPress database user privileges to the minimum required, removing FILE and administrative grants
- Enable WordPress plugin auto-updates for security releases to reduce exposure window on future advisories
