CVE-2024-47335 Overview
CVE-2024-47335 is a SQL Injection vulnerability affecting the Bit Apps Bit Form plugin for WordPress. The flaw stems from improper neutralization of special elements used in SQL commands [CWE-89]. It affects all versions of Bit Form up to and including 2.13.11. An authenticated attacker with high privileges can inject crafted SQL statements through the plugin, resulting in unauthorized access to backend database contents and limited impact on availability. Because the vulnerability crosses a security scope boundary, exploitation can affect resources beyond the vulnerable component itself.
Critical Impact
Authenticated attackers can extract sensitive data from the WordPress database and disrupt plugin availability through crafted SQL payloads sent over the network.
Affected Products
- Bit Apps Bit Form (bit-form) WordPress plugin
- All versions from initial release through 2.13.11
- WordPress installations running the vulnerable plugin

Technical Details for CVE-2024-47335
Vulnerability Analysis
The vulnerability resides in the Bit Form plugin's handling of user-supplied input that is later concatenated into SQL queries. The plugin fails to properly sanitize or parameterize input before passing it to the WordPress database layer. An attacker who holds elevated privileges within the WordPress environment can submit crafted request parameters that break out of the intended query context. This allows execution of attacker-controlled SQL syntax against the underlying database.
The issue is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command. Successful exploitation can expose form submissions, user metadata, and other records stored in the WordPress database. The scope change indicates that impact extends beyond the plugin itself into the broader database and site context.
Root Cause
The root cause is missing input validation and the use of unsafe query construction patterns within the plugin's data-access routines. Input reaches SQL statements without being routed through prepared statements or $wpdb->prepare() with correct placeholders. Special characters such as single quotes, comment sequences, and stacked query separators are not neutralized before query execution.
Attack Vector
Exploitation requires network access to the target WordPress site and an authenticated session with high privileges. The attacker submits crafted parameters to plugin endpoints that process form data. The injected SQL is then executed by the database, allowing extraction of records or manipulation of query logic. No user interaction is required beyond the attacker's own request. The current EPSS estimate places exploitation probability in a relatively low range, but authenticated SQL injection in WordPress plugins is a well-understood attack pattern.

Detection Methods for CVE-2024-47335
Indicators of Compromise
- Unexpected SQL syntax such as UNION SELECT, SLEEP(, or comment sequences (--, /*) in WordPress access logs targeting Bit Form endpoints
- Anomalous database errors referencing wp_bitforms_* tables in PHP or MySQL error logs
- Outbound data transfers from the WordPress host correlated with authenticated administrative sessions
- New or modified administrator accounts created shortly after suspicious plugin requests
Detection Strategies
- Enable WordPress plugin request logging and inspect parameters submitted to Bit Form AJAX and REST endpoints for SQL metacharacters
- Deploy a web application firewall (WAF) rule set that flags SQL injection patterns against /wp-admin/admin-ajax.php and plugin-specific routes
- Monitor MySQL general or slow query logs for unusual UNION, INFORMATION_SCHEMA, or time-based delay queries
Monitoring Recommendations
- Alert on privileged WordPress accounts issuing high volumes of requests to Bit Form endpoints
- Track plugin version inventory across WordPress fleets and flag any host still running Bit Form 2.13.11 or earlier
- Correlate authentication events with subsequent database anomalies to identify compromised administrator sessions
How to Mitigate CVE-2024-47335
Immediate Actions Required
- Update the Bit Form plugin to a version later than 2.13.11 on every WordPress site in the environment
- Audit WordPress user accounts and revoke high-privilege roles that are not strictly required
- Rotate credentials for administrator accounts that could have been used to exploit the flaw
- Review database contents and access logs for signs of prior exploitation
Patch Information
Refer to the Patchstack advisory for the fixed version and vendor patch details. Apply updates through the WordPress plugin management interface or by deploying the vendor-supplied release across all affected sites.
Workarounds
- Temporarily deactivate the Bit Form plugin until a patched release is applied
- Restrict access to WordPress administrative interfaces using IP allow-lists or VPN-only access
- Enforce multi-factor authentication for all high-privilege WordPress accounts to reduce the pool of accounts able to trigger the vulnerability
- Deploy WAF signatures that block SQL injection payloads against Bit Form endpoints as a compensating control
