CVE-2026-2822 identifies a SQL injection vulnerability in JeecgBoot, an open-source rapid development platform widely used for enterprise applications. The vulnerability resides in an unspecified function within the backend interface component, located at the path /jeecgboot/sys/dict/loadDict/airag_app,1,create_by. The issue arises from improper sanitization or validation of the 'keyword' parameter, which is directly incorporated into SQL queries. This flaw allows remote attackers to craft malicious input that alters the intended SQL command structure, enabling unauthorized database queries or modifications. The attack vector is network accessible (AV:N), requires low attack complexity (AC:L), and does not require user interaction (UI:N). However, it requires low privileges (PR:L), meaning an attacker must have some level of authenticated access, though minimal. The vulnerability impacts confidentiality, integrity, and availability of backend data, as attackers could extract sensitive information, modify data, or disrupt services. Although no active exploitation has been reported, the public disclosure of the exploit code increases the likelihood of future attacks. The CVSS 4.0 score of 5.3 reflects a medium severity, balancing the ease of exploitation with the requirement for some privileges and the limited scope of impact. No official patches have been linked yet, so mitigation relies on secure coding practices, input validation, and access controls.

The SQL injection vulnerability in JeecgBoot can have significant impacts on organizations relying on this platform for backend services. Successful exploitation can lead to unauthorized disclosure of sensitive data, including user credentials, business information, or configuration details, compromising confidentiality. Attackers may also alter or delete critical data, undermining data integrity and potentially causing operational disruptions. In some cases, attackers could execute administrative commands on the database, leading to denial of service or further system compromise. Since JeecgBoot is used in enterprise environments, such breaches could result in financial loss, reputational damage, regulatory penalties, and operational downtime. The requirement for low privileges reduces the barrier for exploitation, especially in environments with weak access controls. The lack of user interaction needed means automated attacks or worm-like propagation within vulnerable networks are possible. Although currently no known exploits are active in the wild, the public availability of exploit details increases risk, making timely mitigation essential.

To mitigate CVE-2026-2822, organizations should first upgrade JeecgBoot to a version where this vulnerability is patched once available. In the absence of an official patch, immediate steps include implementing strict input validation and sanitization on the 'keyword' parameter in the affected backend interface to prevent malicious SQL code injection. Employ parameterized queries or prepared statements in the database access layer to eliminate direct concatenation of user inputs into SQL commands. Restrict access to the vulnerable backend interface by enforcing strong authentication and authorization controls, limiting the ability of low-privilege users to reach this endpoint. Monitor logs for unusual database query patterns or repeated failed attempts indicative of injection attempts. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting this specific endpoint. Conduct thorough code reviews and security testing focusing on input handling in the affected components. Finally, educate developers on secure coding practices to prevent similar vulnerabilities in future releases.
