CVE-2026-61955 Overview
CVE-2026-61955 is a Blind SQL Injection vulnerability in the Hannan persian-gravity-forms (گرویتی فرم فارسی) WordPress plugin. The flaw affects all versions up to and including 3.0.2. The vulnerability is classified as [CWE-89]: Improper Neutralization of Special Elements used in an SQL Command.
An authenticated attacker with high privileges can inject arbitrary SQL statements into backend database queries. Successful exploitation results in full disclosure of database contents and limited availability impact. The vulnerability has a scope change component, meaning the impact extends beyond the vulnerable component itself.
Critical Impact
Attackers can extract sensitive data from the WordPress database, including user credentials, form submissions, and site configuration data, through blind SQL injection techniques.
Affected Products
- Hannan گرویتی فرم فارسی (persian-gravity-forms) WordPress plugin versions through 3.0.2
- WordPress installations using the affected plugin
- Sites relying on Persian localization of Gravity Forms via this plugin

Technical Details for CVE-2026-61955
Vulnerability Analysis
The vulnerability is a Blind SQL Injection flaw in the persian-gravity-forms plugin. The plugin fails to properly neutralize user-supplied input before incorporating it into SQL queries executed against the WordPress database.
Because the injection is blind, attackers do not receive direct database output in HTTP responses. Instead, they infer data by observing application behavior, response differences, or timing delays. Boolean-based and time-based inference techniques allow full data extraction over automated request sequences.
The attack requires high privileges, indicating an authenticated administrator or comparable role must trigger the vulnerable code path. The scope change flag reflects the ability of the injected query to affect data outside the plugin's own security boundary, including other WordPress tables shared across the database.
Root Cause
The root cause is missing or insufficient parameterization of SQL queries built from request parameters. The plugin concatenates untrusted input directly into query strings rather than using prepared statements or the WordPress $wpdb->prepare() API with proper placeholders. Refer to the Patchstack SQL Injection Advisory for advisory details.
Attack Vector
The attack vector is network-based over HTTP or HTTPS to the WordPress admin interface. An attacker with valid high-privilege credentials sends crafted requests containing SQL metacharacters and inference payloads to the vulnerable endpoint. No user interaction is required beyond the attacker's own authenticated session.
No verified public exploit code is available. See the linked Patchstack advisory for technical specifics on the affected parameter and endpoint.
Detection Methods for CVE-2026-61955
Indicators of Compromise
- Unusual HTTP requests to WordPress admin endpoints containing SQL keywords such as UNION, SELECT, SLEEP, BENCHMARK, or encoded variants
- Repeated requests from a single authenticated session with incremental payload variations characteristic of blind SQLi automation
- Elevated database query latency correlated with admin-panel activity from a specific user account
Detection Strategies
- Deploy a Web Application Firewall (WAF) with SQL injection signatures tuned for WordPress admin traffic
- Enable MySQL general query log or slow query log to identify anomalous query structures originating from the plugin
- Correlate WordPress wp-admin access logs against database error logs to surface failed injection attempts
Monitoring Recommendations
- Alert on administrator accounts issuing atypical volumes of requests to plugin endpoints
- Monitor for time-based patterns of SLEEP() or BENCHMARK() calls in query logs
- Track modifications to sensitive tables such as wp_users and wp_options outside of expected administrative workflows
How to Mitigate CVE-2026-61955
Immediate Actions Required
- Identify all WordPress sites running the persian-gravity-forms plugin at version 3.0.2 or earlier
- Deactivate and remove the plugin until a patched version is confirmed available
- Rotate credentials for all WordPress administrator accounts and audit recent admin activity
- Review database contents and access logs for signs of unauthorized data extraction
Patch Information
At time of publication, the NVD entry lists affected versions through <= 3.0.2 without a confirmed fixed release identifier. Consult the Patchstack SQL Injection Advisory for current patch availability and upgrade guidance.
Workarounds
- Restrict access to the WordPress admin interface using IP allowlisting or a VPN
- Enforce strong multi-factor authentication for all administrator accounts to reduce the risk of credential-based exploitation
- Deploy WAF rules that block SQL injection payloads targeting the plugin's request parameters
- Apply the principle of least privilege to the database user account used by WordPress, limiting unnecessary permissions
# Example: disable the vulnerable plugin via WP-CLI until a patch is available
wp plugin deactivate persian-gravity-forms
wp plugin delete persian-gravity-forms
