CVE-2025-39370 is a high-severity SQL Injection vulnerability (CWE-89) found in the Cnilsson iCafe Library, affecting versions up to 1.8.3. SQL Injection occurs when untrusted input is improperly sanitized or neutralized before being included in SQL commands, allowing an attacker to manipulate the query structure. This can lead to unauthorized access or manipulation of the underlying database. According to the CVSS 3.1 vector (7.6), the vulnerability is remotely exploitable over the network (AV:N) with low attack complexity (AC:L), but requires high privileges (PR:H) and no user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact is high on confidentiality (C:H), no impact on integrity (I:N), and low impact on availability (A:L). This suggests that an attacker with high privileges can exploit the vulnerability to extract sensitive data from the database without altering data or significantly disrupting service. No known exploits are currently in the wild, and no patches have been published yet. The vulnerability was reserved in April 2025 and published in May 2025. The iCafe Library is a software component likely used in web applications or services that rely on SQL databases, and improper neutralization of SQL commands can allow attackers to execute arbitrary SQL queries, potentially exposing sensitive information or enabling further attacks.

For European organizations using the Cnilsson iCafe Library, this vulnerability poses a significant risk to the confidentiality of their data. Since the vulnerability requires high privileges, it is likely exploitable by insiders or attackers who have already gained elevated access, such as through compromised credentials or privilege escalation. The ability to extract sensitive data from databases can lead to data breaches involving personal data protected under GDPR, intellectual property theft, or exposure of confidential business information. The low impact on availability means service disruption is less likely, but the confidentiality breach alone can have severe regulatory and reputational consequences. Organizations in sectors with strict data protection requirements, such as finance, healthcare, and government, are particularly at risk. The lack of patches increases the urgency for mitigation. Additionally, the changed scope indicates that exploitation could affect other components or services beyond the iCafe Library itself, potentially amplifying the impact.

1. Immediate mitigation should include restricting access to systems running the vulnerable iCafe Library to trusted and authenticated users only, minimizing the risk of privilege escalation. 2. Implement strict input validation and sanitization at the application level to prevent malicious SQL code from being processed. 3. Employ the principle of least privilege to limit user and service account permissions, reducing the potential impact if an account is compromised. 4. Monitor database queries and logs for unusual or unauthorized access patterns indicative of SQL Injection attempts. 5. If possible, isolate the affected components in network segments with limited exposure. 6. Engage with the vendor or community to obtain patches or updates as soon as they become available. 7. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection payloads targeting the iCafe Library. 8. Conduct security audits and penetration testing focused on SQL Injection vectors in applications using the iCafe Library. 9. Prepare incident response plans to quickly contain and remediate any exploitation attempts.
