Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing uses SQL injection payloads against database interfaces, identifying and supporting fixes for SQL injection weaknesses.
Developer assessments and testing (including injection-focused techniques) identify improper neutralization of special elements, and the verifiable flaw remediation corrects them pre-deployment.
Validates query inputs to prevent SQL syntax or command manipulation.
Identifies indicators of injection attacks (command, SQL, LDAP, etc.) via anomaly and attack monitoring.
MITRE ATT&CK Enterprise TechniquesAI
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.
NVD Description
A security vulnerability has been detected in JeecgBoot up to 3.9.1. The affected element is an unknown function of the file /jeecgboot/sys/dict/loadDict/airag_app,1,create_by of the component Backend Interface. Such manipulation of the argument keyword leads to sql injection. The attack can…

Deeper analysisAI
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).
