CVE-2025-8536 is a critical security vulnerability classified under CWE-89 (SQL Injection) affecting older branches of DobryCMS, a content management system developed by Studio Fabryka. The vulnerability stems from improper neutralization of special elements in user-supplied input within the language functionality of the CMS. This flaw allows an unauthenticated attacker to craft malicious SQL queries that the backend database executes, potentially leading to unauthorized data disclosure, data modification, or even complete compromise of the underlying database. The vulnerability is remotely exploitable without any user interaction or privileges, as indicated by the CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N). The impact on confidentiality and integrity is high, while availability impact is low. Although no public exploits have been reported yet, the critical CVSS score of 9.3 reflects the severity and ease of exploitation. The vulnerability affects older versions (version 0 indicated) of DobryCMS, suggesting that newer versions may have addressed the issue. The lack of available patches at the time of publication necessitates immediate defensive measures. The vulnerability was assigned and published by CERT-PL, indicating regional awareness and possibly higher usage in Poland. SQL injection vulnerabilities remain a common and dangerous attack vector, often exploited to gain unauthorized access to sensitive information or to escalate privileges within the affected system.

For European organizations using DobryCMS, this vulnerability poses a significant risk of data breaches, unauthorized data manipulation, and potential full compromise of backend databases. Confidentiality and integrity of sensitive data stored in DobryCMS installations can be severely impacted, leading to exposure of personal data, intellectual property, or business-critical information. The vulnerability's remote and unauthenticated exploitability increases the attack surface, allowing attackers to target vulnerable systems over the internet without requiring user credentials or interaction. This can lead to regulatory compliance issues under GDPR due to potential personal data exposure. Additionally, compromised CMS platforms can be leveraged to distribute malware or conduct further attacks within organizational networks. The absence of known exploits in the wild currently provides a limited window for mitigation before active exploitation emerges. Organizations relying on DobryCMS for web content management, especially those with public-facing installations, are at heightened risk.

1. Immediate upgrade to the latest version of DobryCMS where this vulnerability is patched; if no patch is available, consider migrating to alternative CMS platforms. 2. Implement strict input validation and sanitization on all user inputs, especially those related to language or localization features. 3. Employ parameterized queries or prepared statements in database interactions to prevent SQL injection. 4. Restrict database user permissions to the minimum necessary, avoiding use of highly privileged accounts by the CMS. 5. Monitor web application logs for suspicious SQL query patterns or unusual database errors indicative of attempted injection. 6. Deploy Web Application Firewalls (WAFs) with rules specifically designed to detect and block SQL injection attempts targeting DobryCMS. 7. Conduct regular security assessments and penetration testing focusing on injection flaws. 8. Educate developers and administrators on secure coding practices and the risks of SQL injection. 9. Isolate DobryCMS installations in segmented network zones to limit lateral movement if compromised. 10. Prepare incident response plans to quickly address potential exploitation events.
