CVE-2025-59570 Overview
CVE-2025-59570 is a SQL Injection vulnerability in the WPFunnels Mail Mint WordPress plugin. The flaw stems from improper neutralization of special elements used in an SQL command [CWE-89]. It affects all versions of Mail Mint up to and including 1.18.6. An authenticated attacker with high privileges can inject SQL statements over the network to read sensitive database contents and impact availability. The vulnerability was published to the National Vulnerability Database (NVD) on September 22, 2025.
Critical Impact
Authenticated attackers can execute arbitrary SQL queries against the WordPress database, exposing confidential data and disrupting service.
Affected Products
- WPFunnels Mail Mint plugin for WordPress
- All versions through 1.18.6
- WordPress sites with the mail-mint plugin installed

Technical Details for CVE-2025-59570
Vulnerability Analysis
The vulnerability is classified under [CWE-89], Improper Neutralization of Special Elements used in an SQL Command. Mail Mint accepts attacker-controlled input and incorporates it into SQL queries without adequate sanitization or parameterization. The flaw is reachable over the network and requires an authenticated session with high privileges. The scope is changed, meaning the impact extends beyond the vulnerable component to other WordPress database tables. Successful exploitation results in high confidentiality impact and partial availability impact, with no direct integrity impact reported.
According to the Exploit Prediction Scoring System (EPSS), the probability of exploitation in the next 30 days is approximately 0.331%.
Root Cause
The root cause is the use of unsanitized input within SQL query construction inside the Mail Mint plugin. User-supplied parameters are concatenated into queries rather than passed through prepared statements or the WordPress $wpdb->prepare() API. This allows special SQL characters to break out of the intended query context and modify query logic.
Attack Vector
An attacker authenticates to the WordPress site with a privileged account and submits crafted input to a Mail Mint endpoint that interacts with the database. The injected payload alters the SQL statement to return arbitrary rows, enumerate schema, or trigger resource-intensive queries. Because the scope is changed, impact may extend to data outside the plugin's own tables, including WordPress user records.
No public proof-of-concept exploit code has been verified for this CVE. Refer to the Patchstack WordPress Vulnerability Report for additional technical context.
Detection Methods for CVE-2025-59570
Indicators of Compromise
- Unexpected SQL keywords (UNION, SELECT, SLEEP, BENCHMARK) in HTTP request parameters sent to Mail Mint endpoints
- Anomalous database query patterns or sudden spikes in query duration originating from the mail-mint plugin context
- Web server access logs showing requests to Mail Mint admin AJAX or REST endpoints from privileged accounts at unusual times
Detection Strategies
- Inspect WordPress and web application firewall (WAF) logs for SQL metacharacters in parameters consumed by the mail-mint plugin
- Enable MySQL general query logging temporarily to identify malformed or suspicious queries originating from the plugin
- Compare the installed mail-mint plugin version against 1.18.6 to identify vulnerable instances
Monitoring Recommendations
- Alert on authenticated administrator activity that triggers database errors or unusually long-running queries
- Monitor for privilege changes or new administrator accounts that may follow successful SQL injection
- Track outbound data transfers from the database host to detect bulk data exfiltration
How to Mitigate CVE-2025-59570
Immediate Actions Required
- Update the Mail Mint plugin to a version later than 1.18.6 once the vendor publishes a fix
- Audit WordPress administrator and editor accounts and remove unused privileged users
- Rotate database credentials and WordPress user passwords if compromise is suspected
- Review the database for unauthorized rows, modified user roles, or unexpected schema changes
Patch Information
The issue affects Mail Mint versions through 1.18.6. Consult the Patchstack WordPress Vulnerability Report for the latest patch availability and vendor guidance.
Workarounds
- Deactivate the Mail Mint plugin until a patched version is installed
- Restrict access to the WordPress administrative interface using IP allowlists or VPN-only access
- Deploy a web application firewall rule to block SQL injection patterns targeting mail-mint endpoints
- Apply the principle of least privilege by limiting which users hold the high-privilege roles required for exploitation
