CVE-2026-2822
Published: 20 February 2026
Summary
CVE-2026-2822 is a medium-severity Injection (CWE-74) vulnerability in Jeecg Jeecg Boot. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 27.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).
Deeper analysis
CVE-2026-2822 is a SQL injection vulnerability in JeecgBoot versions up to 3.9.1. The flaw affects an unknown function in the file /jeecgboot/sys/dict/loadDict/airag_app,1,create_by within the Backend Interface component, where manipulation of the "keyword" argument triggers the injection.
The vulnerability enables remote exploitation over the network with low attack complexity, requiring low privileges such as an authenticated user account and no user interaction. Attackers can achieve low impacts on confidentiality, integrity, and availability, resulting in a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L). It maps to CWE-74 (improper neutralization of special elements in an SQL command) and CWE-89 (SQL injection).

Why these techniques?
SQL injection in a remotely accessible web backend interface (JeecgBoot) is a classic vector for initial access by exploiting a public-facing or network-exposed application vulnerability.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of the keyword argument to reject or neutralize special characters that enable SQL injection in the loadDict endpoint.
Restricts the low-privilege authenticated accounts that can reach the vulnerable backend interface, reducing the attack surface and potential impact.
Enables monitoring of database queries and input anomalies originating from the /jeecgboot/sys/dict/loadDict path to identify injection attempts.
