CVE-2025-62606 is an SQL injection vulnerability classified under CWE-89 affecting My-Little-Forum, a PHP and MySQL-based internet forum software. The flaw exists in the bookmark reordering feature prior to version 2.5.12, where insufficient input sanitization allows authenticated users to inject malicious SQL commands. Since the vulnerability requires only authenticated access but no additional user interaction, any logged-in user can exploit it to execute arbitrary SQL queries. This can lead to a full compromise of the forum's backend database, enabling attackers to read sensitive data, modify or delete records, and potentially escalate privileges within the application. The vulnerability has a CVSS v3.1 base score of 8.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no user interaction required. Although no public exploits have been reported yet, the presence of this vulnerability in widely deployed forum software poses a significant risk. The issue was publicly disclosed on October 22, 2025, and fixed in version 2.5.12. Organizations running affected versions should apply the patch immediately to prevent exploitation. The vulnerability's exploitation could also facilitate further attacks on the hosting environment or connected systems if database credentials or other sensitive information is compromised.

For European organizations, this vulnerability poses a significant threat to the confidentiality, integrity, and availability of forum data. Compromise of the database could lead to leakage of sensitive user information, manipulation of forum content, or deletion of critical data, undermining trust and operational continuity. Organizations using My-Little-Forum for internal or public communication may face reputational damage, legal liabilities under GDPR due to data breaches, and potential disruption of services. Attackers exploiting this vulnerability could also leverage the compromised database to pivot to other internal systems, increasing overall risk. Given the authenticated nature of the exploit, insider threats or compromised user accounts could be used to launch attacks. The impact is heightened in sectors where forums are used for sensitive discussions, such as government, healthcare, or financial services within Europe.

1. Immediately upgrade all My-Little-Forum installations to version 2.5.12 or later to apply the official patch addressing this vulnerability. 2. Restrict forum user privileges to the minimum necessary, especially limiting bookmark reordering capabilities to trusted users where possible. 3. Implement strong authentication mechanisms and monitor for unusual login patterns to detect potential misuse of authenticated accounts. 4. Conduct regular database activity monitoring and logging to identify suspicious SQL queries indicative of injection attempts. 5. Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting the bookmark reordering feature. 6. Review and harden database user permissions to limit the impact of any successful injection. 7. Educate forum administrators and users about the risks of SQL injection and the importance of applying security updates promptly. 8. Perform periodic security assessments and penetration testing focused on input validation and authentication controls within the forum application.
