CVE-2025-22350 Overview
CVE-2025-22350 is a SQL Injection vulnerability in the WpIndeed Ultimate Learning Pro WordPress plugin. The flaw affects all versions of Ultimate Learning Pro through version 3.9. An authenticated attacker with high privileges can inject crafted SQL statements through unsanitized input handled by the plugin. Successful exploitation enables access to confidential database records and can cause limited availability impact on the affected WordPress instance. The vulnerability is categorized under [CWE-89] Improper Neutralization of Special Elements used in an SQL Command.
Critical Impact
Authenticated attackers can extract sensitive data from the WordPress database and impact site availability through crafted SQL payloads against the Ultimate Learning Pro plugin.
Affected Products
- WpIndeed Ultimate Learning Pro plugin for WordPress
- All versions from unspecified initial release through 3.9
- WordPress sites with the Ultimate Learning Pro plugin enabled

Technical Details for CVE-2025-22350
Vulnerability Analysis
The vulnerability stems from improper neutralization of special characters in SQL statements processed by the Ultimate Learning Pro plugin. User-supplied input reaches a database query without sufficient sanitization or parameterization. An attacker with elevated privileges on the WordPress instance can manipulate query logic to read arbitrary tables. The scope is marked as changed, meaning the impact extends beyond the vulnerable component into the broader WordPress environment. Confidentiality impact is high because attackers can retrieve user records, password hashes, and session data stored in WordPress tables.
Root Cause
The plugin code constructs SQL queries by concatenating untrusted parameters instead of using prepared statements or the WordPress $wpdb->prepare() API. This pattern allows special characters such as single quotes and SQL keywords to alter query structure.
Attack Vector
Exploitation requires network access to the WordPress site and authenticated access with high privileges. The attacker submits crafted parameters to a vulnerable plugin endpoint. The injected SQL executes within the database context used by the plugin. No user interaction is required to trigger the payload once the request is sent. Refer to the Patchstack SQL Injection Vulnerability advisory for additional technical context.
Detection Methods for CVE-2025-22350
Indicators of Compromise
- Unexpected SQL syntax such as UNION SELECT, SLEEP(, or INFORMATION_SCHEMA appearing in HTTP request parameters to Ultimate Learning Pro endpoints
- Database error messages returned in HTTP responses from /wp-admin/ or plugin AJAX handlers
- Anomalous outbound database queries originating from the WordPress process during authenticated administrator sessions
Detection Strategies
- Inspect web server access logs for requests targeting Ultimate Learning Pro routes that contain SQL metacharacters or encoded payloads
- Deploy a Web Application Firewall (WAF) ruleset that matches SQL Injection signatures against POST and GET parameters
- Enable WordPress query logging to capture malformed or excessively long SQL statements issued by the plugin
Monitoring Recommendations
- Alert on privilege escalation events or new administrator account creation following suspicious requests to plugin endpoints
- Monitor database read volume from the WordPress user for sudden spikes indicative of data exfiltration
- Track plugin file integrity to identify post-exploitation modifications to PHP source files
How to Mitigate CVE-2025-22350
Immediate Actions Required
- Identify all WordPress sites running Ultimate Learning Pro version 3.9 or earlier
- Restrict administrative access to trusted IP ranges until the plugin is updated
- Rotate credentials and session tokens for accounts that may have been used to exploit the flaw
Patch Information
At the time of NVD publication, the advisory lists affected versions through 3.9. Review the Patchstack advisory for the latest fixed version information and apply the vendor-supplied update once available.
Workarounds
- Disable the Ultimate Learning Pro plugin until a patched version is installed
- Apply WAF virtual patching rules that block SQL Injection payloads targeting plugin parameters
- Enforce the principle of least privilege by limiting which accounts hold the elevated WordPress roles required to reach the vulnerable code path
# Configuration example: disable the plugin via WP-CLI until patched
wp plugin deactivate indeed-learning-pro
wp plugin status indeed-learning-pro
