Published: 01 April 2026
Summary
CVE-2024-40489 is a critical-severity Code Injection (CWE-94) vulnerability in Jeecg Jeecg Boot. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 40.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2024-40489 is an injection vulnerability (CWE-94) in jeecg boot versions 3.0.0 through 3.5.3, caused by lax character filtering. This flaw allows attackers to execute arbitrary code on affected components through specially crafted HTTP requests. The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), marking it as critical due to its high impact on confidentiality, integrity, and availability.
Any unauthenticated attacker with network access can exploit this vulnerability, as it requires low attack complexity and no user interaction or privileges. Exploitation involves sending malicious HTTP requests that bypass filtering, leading to remote arbitrary code execution on the targeted jeecg boot instance.
