CVE-2025-59570 is a high-severity SQL Injection vulnerability (CWE-89) affecting WPFunnels Mail Mint, a software product used for email marketing and funnel management. The vulnerability arises from improper neutralization of special elements in SQL commands, allowing an attacker with high privileges (PR:H) to inject malicious SQL code remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality severely (C:H), with no impact on integrity (I:N) and a low impact on availability (A:L). The scope is changed (S:C), indicating that the vulnerability can affect resources beyond the initially vulnerable component. The affected versions include all versions up to 1.18.6. Although no known exploits are currently reported in the wild, the vulnerability's nature and CVSS score of 7.6 indicate a significant risk. Exploitation requires authenticated access with high privileges, which suggests that attackers would need to compromise or have legitimate access to a user account with elevated permissions within the Mail Mint system. Successful exploitation could allow attackers to extract sensitive data from the backend database, potentially exposing confidential customer information or internal business data. The SQL Injection flaw does not appear to allow modification of data or denial of service but could lead to data leakage and privacy violations. The vulnerability was published on September 22, 2025, and no patches or mitigation links are currently provided, indicating that organizations must proactively assess and secure their deployments. Given the nature of Mail Mint as an email marketing tool, the backend database likely contains customer contact details, campaign data, and possibly user credentials, making confidentiality breaches particularly damaging.

For European organizations using WPFunnels Mail Mint, this vulnerability poses a significant risk to the confidentiality of customer and business data. Exposure of sensitive information could lead to regulatory non-compliance, especially under GDPR, resulting in legal penalties and reputational damage. Attackers exploiting this vulnerability could access personal data of EU citizens, triggering mandatory breach notifications and undermining customer trust. Furthermore, email marketing platforms are often integrated with other business systems; thus, data leakage could facilitate further attacks or fraud. The requirement for high privilege authentication reduces the risk of widespread exploitation but highlights the importance of internal threat management and account security. Organizations in sectors such as retail, finance, and healthcare that rely on email marketing and customer data management are particularly vulnerable. The lack of available patches increases the urgency for immediate mitigation to prevent potential exploitation.

1. Restrict and monitor high-privilege user accounts within Mail Mint to minimize the risk of credential compromise. 2. Implement strong authentication mechanisms, including multi-factor authentication (MFA), to protect privileged accounts. 3. Conduct thorough input validation and sanitization on all user inputs interacting with the database, even if patches are not yet available. 4. Employ Web Application Firewalls (WAFs) with SQL Injection detection and prevention capabilities to block malicious payloads targeting Mail Mint. 5. Regularly audit database access logs for unusual queries or access patterns indicative of exploitation attempts. 6. Segment the network and database access to limit the blast radius if an account is compromised. 7. Monitor vendor communications closely for patch releases and apply updates promptly once available. 8. Consider temporary disabling or limiting the use of vulnerable Mail Mint features if feasible until a patch is released. 9. Educate internal users about phishing and credential security to reduce the risk of privilege escalation. 10. Perform penetration testing focused on SQL Injection vectors within Mail Mint deployments to identify and remediate weaknesses proactively.
