The vulnerability identified as CVE-2025-64493 affects SuiteCRM-Core, an open-source CRM platform widely used by enterprises. Specifically, versions 8.6.0 through 8.9.0 contain an authenticated, blind SQL injection flaw in the appMetadata operation of the GraphQL API. This flaw arises from improper neutralization of special elements in SQL commands (CWE-89), enabling attackers with valid user credentials (but not requiring administrative privileges) to perform time-based blind SQL injection attacks. Exploiting this vulnerability allows attackers to extract arbitrary data from the backend database, compromising confidentiality. The attack vector is remote network access (AV:N), requires low attack complexity (AC:L), and no user interaction (UI:N). The vulnerability does not allow modification or deletion of data (integrity unaffected) nor does it impact system availability. The issue was publicly disclosed on November 8, 2025, and fixed in SuiteCRM version 8.9.1. No known exploits are reported in the wild yet. The CVSS v3.1 base score is 6.5, reflecting a medium severity level primarily due to the confidentiality impact and ease of exploitation by authenticated users.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive customer and business data stored within SuiteCRM databases. Since SuiteCRM is used by various sectors including finance, healthcare, and public services across Europe, unauthorized data extraction could lead to exposure of personal data protected under GDPR, resulting in regulatory penalties and reputational damage. The fact that the vulnerability requires only authenticated user access but not administrative privileges broadens the potential attacker base, including insider threats or compromised user accounts. Although the vulnerability does not affect data integrity or availability, the loss of confidentiality could facilitate further attacks or data misuse. Organizations relying on SuiteCRM versions prior to 8.9.1 should consider this a priority risk, especially those with high-value or regulated data.

European organizations should immediately upgrade all affected SuiteCRM-Core instances to version 8.9.1 or later, where the vulnerability is patched. Until upgrade is possible, implement strict access controls to limit user privileges and monitor GraphQL API usage for unusual query patterns indicative of SQL injection attempts. Employ Web Application Firewalls (WAFs) with rules targeting SQL injection in GraphQL endpoints. Conduct thorough audits of user accounts to detect and disable compromised or unnecessary accounts. Additionally, enable detailed logging and alerting on database query anomalies. Regularly review and update incident response plans to address potential data breaches stemming from this vulnerability. Finally, ensure that backups are securely maintained to support recovery in case of exploitation.
