CVE-2025-30571 Overview
CVE-2025-30571 is a SQL injection vulnerability in the STEdb Forms WordPress plugin developed by STEdb Corp. The flaw affects all versions of stedb-forms up to and including 1.0.4. Attackers with high privileges can inject malicious SQL statements through unsanitized input handled by the plugin. Successful exploitation can expose database contents, alter query logic, and impact data integrity within the WordPress backend. The issue is tracked under CWE-89: Improper Neutralization of Special Elements used in an SQL Command.
Critical Impact
Authenticated attackers can execute arbitrary SQL queries against the WordPress database, leading to confidentiality loss and potential service disruption.
Affected Products
- STEdb Corp STEdb Forms plugin for WordPress
- All versions from initial release through 1.0.4
- WordPress sites with stedb-forms installed and active
Discovery Timeline

Technical Details for CVE-2025-30571
Vulnerability Analysis
The vulnerability resides in the STEdb Forms plugin code paths that build SQL queries from user-supplied parameters. The plugin fails to neutralize special characters before concatenating input into SQL statements. An attacker authenticated with high privileges can submit crafted parameters that break out of the intended query context. This results in arbitrary SQL execution against the WordPress database backend.
The Exploit Prediction Scoring System rates the probability of exploitation at 0.516% as of June 2026. No public proof-of-concept exploit has been published, and the issue is not listed in the CISA Known Exploited Vulnerabilities catalog. The advisory was coordinated through Patchstack, which catalogs WordPress plugin vulnerabilities.
Root Cause
The root cause is improper input neutralization within database query construction [CWE-89]. The plugin concatenates request parameters directly into SQL statements rather than using prepared statements with bound parameters. WordPress provides $wpdb->prepare() for safe query construction, but the affected code paths bypass this safeguard.
Attack Vector
Exploitation occurs over the network through authenticated HTTP requests to plugin endpoints. The attacker must hold high-privilege credentials, such as administrator-level access, to reach the vulnerable functionality. Because the scope is changed, successful exploitation can affect resources beyond the vulnerable component. The impact is rated as high confidentiality loss with low availability impact and no direct integrity impact.
No verified exploitation code is publicly available. See the Patchstack SQL Injection Advisory for additional technical context.
Detection Methods for CVE-2025-30571
Indicators of Compromise
- Unexpected SQL syntax tokens such as UNION SELECT, OR 1=1, or comment markers (--, /*) appearing in HTTP request parameters targeting stedb-forms endpoints
- Anomalous database read volumes originating from the WordPress application user
- Administrator account activity submitting form data outside normal usage patterns
- Web server access logs showing repeated requests to plugin URLs with encoded payloads
Detection Strategies
- Inspect WordPress access logs for requests to stedb-forms plugin paths containing SQL metacharacters
- Enable MySQL general query logging temporarily to identify malformed or chained statements originating from the plugin
- Deploy a web application firewall ruleset that flags SQL injection signatures against WordPress plugin endpoints
- Monitor for sudden growth in response sizes from plugin endpoints, which can indicate data exfiltration via injection
Monitoring Recommendations
- Alert on administrator-level sessions interacting with stedb-forms outside maintenance windows
- Track schema enumeration patterns such as queries referencing information_schema from the WordPress database user
- Forward WordPress, web server, and database logs to a centralized analytics platform for correlation
How to Mitigate CVE-2025-30571
Immediate Actions Required
- Identify all WordPress installations running the STEdb Forms plugin and inventory the installed version
- Deactivate the stedb-forms plugin on any site running version 1.0.4 or earlier until a patched release is verified
- Restrict administrator account access and rotate credentials for high-privilege WordPress users
- Review database audit logs for evidence of unauthorized queries originating from the WordPress application
Patch Information
As of the latest NVD update, the advisory lists the vulnerability as affecting STEdb Forms up to and including version 1.0.4. Monitor the Patchstack advisory and the WordPress plugin repository for a fixed release. Apply the vendor patch on all WordPress instances once it is published and validated.
Workarounds
- Deactivate and remove the stedb-forms plugin until a fixed version is available
- Apply web application firewall rules that block SQL injection patterns against WordPress plugin endpoints
- Limit administrator accounts to trusted personnel and enforce multi-factor authentication on all privileged WordPress logins
- Restrict database privileges for the WordPress application user to the minimum required tables and operations
