CVE-2026-2122 identifies a SQL injection vulnerability in the Xiaopi Panel product, affecting versions up to 20260126. The vulnerability is located in the /demo.php file within the WAF Firewall component, where the 'ID' parameter is improperly sanitized, allowing attackers to inject arbitrary SQL commands. This flaw can be exploited remotely without requiring user interaction or elevated privileges, though low privileges are necessary. The injection could enable attackers to read, modify, or delete database contents, potentially compromising confidentiality and integrity of data managed by the panel. The vendor has not responded to disclosure requests and no official patches have been released, but public exploit code is available, increasing the risk of exploitation. The CVSS 4.0 score of 5.3 reflects a medium severity, considering the ease of exploitation (low complexity), lack of required user interaction, and limited scope confined to the affected component. The vulnerability does not affect system availability directly but poses a significant risk to data confidentiality and integrity. The Xiaopi Panel is used for managing web application firewall settings, so compromise could also facilitate further attacks or bypass security controls. The absence of vendor response and patching elevates the urgency for organizations to implement mitigations and monitor for exploitation attempts.

For European organizations, exploitation of CVE-2026-2122 could lead to unauthorized access to sensitive configuration data or user information stored within the Xiaopi Panel database. This may result in data breaches, loss of data integrity, or unauthorized modification of firewall rules, potentially exposing networks to further attacks. Organizations relying on Xiaopi Panel for web application firewall management could see a degradation of their security posture, increasing the risk of downstream compromises. The impact is particularly critical for sectors handling sensitive personal data under GDPR, as data breaches could lead to regulatory penalties and reputational damage. Additionally, attackers could leverage the vulnerability to establish persistence or pivot within networks. The medium severity suggests a moderate but tangible risk, especially given the availability of public exploits and lack of vendor patching. European entities with limited cybersecurity resources or delayed patch management processes are at higher risk of successful exploitation.

Given the absence of an official patch, European organizations should immediately implement the following mitigations: 1) Apply strict input validation and sanitization on the 'ID' parameter at the application or proxy level to block malicious SQL payloads. 2) Deploy or fine-tune existing web application firewalls (WAFs) to detect and block SQL injection attempts targeting /demo.php and related endpoints. 3) Restrict network access to the Xiaopi Panel interface to trusted IP addresses or VPNs to reduce exposure. 4) Monitor logs and network traffic for unusual queries or access patterns indicative of SQL injection attempts. 5) Conduct regular security assessments and penetration tests focusing on the Xiaopi Panel environment. 6) Isolate the Xiaopi Panel server from critical infrastructure to limit lateral movement if compromised. 7) Engage with the vendor or community for updates and consider alternative solutions if patching is delayed. 8) Educate administrators on the risks and signs of exploitation to enable rapid incident response.
