CVE-2025-61194 identifies a SQL injection vulnerability in daicuocms version 1.3.13, specifically located in the file library\think\db\Builder.php. SQL injection vulnerabilities occur when untrusted input is improperly sanitized and incorporated into SQL queries, allowing attackers to manipulate the query logic. This can lead to unauthorized data retrieval, data modification, or even complete compromise of the backend database. The vulnerability was reserved on September 26, 2025, and published on October 21, 2025, but currently lacks a CVSS score and no public exploits have been reported. The affected component, Builder.php, is likely responsible for constructing database queries, making it a critical point for injection attacks. The absence of a patch link suggests that a fix may not yet be publicly available, increasing the urgency for organizations to implement interim mitigations such as input validation and query parameterization. This vulnerability can be exploited remotely without authentication or user interaction, increasing its risk profile. Attackers exploiting this flaw could extract sensitive information, alter or delete data, or escalate privileges within the affected system. The impact is primarily on confidentiality and integrity, with potential availability impacts if the database is disrupted. Organizations using daicuocms 1.3.13, especially in web-facing roles, should prioritize assessment and mitigation.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive data managed through daicuocms-based web applications. Exploitation could lead to unauthorized access to customer data, intellectual property, or internal business information, potentially resulting in regulatory non-compliance under GDPR and reputational damage. The ability to manipulate database queries without authentication increases the threat level, as attackers can operate remotely and anonymously. Disruption of database availability could also impact business continuity. Organizations in sectors such as finance, healthcare, e-commerce, and government, which often handle sensitive personal or financial data, are particularly vulnerable. The lack of a current patch means organizations must rely on compensating controls, increasing operational overhead. Additionally, the vulnerability could be leveraged as a foothold for further network intrusion or lateral movement within corporate environments. The overall impact is heightened by the widespread use of CMS platforms in Europe and the critical nature of data processed by these systems.

1. Immediately audit all instances of daicuocms to identify deployments of version 1.3.13 or other potentially vulnerable versions. 2. Implement strict input validation and sanitization on all user-supplied data, especially those interacting with database queries. 3. Employ parameterized queries or prepared statements to prevent injection attacks at the code level. 4. Monitor web application logs for unusual database query patterns or errors indicative of injection attempts. 5. Restrict database user permissions to the minimum necessary to limit the impact of a successful injection. 6. Apply web application firewalls (WAFs) with rules designed to detect and block SQL injection attempts. 7. Stay alert for official patches or updates from daicuocms maintainers and apply them promptly once available. 8. Conduct regular security assessments and penetration testing focused on injection vulnerabilities. 9. Educate developers and administrators on secure coding practices and the risks of SQL injection. 10. Consider isolating critical databases behind additional network segmentation to reduce exposure.
