2DescriptionNVD
A vulnerability was identified in JeecgBoot up to 3.9.1. The impacted element is an unknown function of the file /sys/comment/add. Such manipulation leads to improper access controls. The attack can be executed remotely. The exploit is publicly available and might be used. Upgrading to version 3.9.2 is sufficient to resolve this issue. Upgrading the affected component is recommended.
AnalysisAI
Improper access control in JeecgBoot versions up to 3.9.1 allows low-privileged authenticated remote users to interact with the /sys/comment/add endpoint beyond their assigned permission level, resulting in low-impact confidentiality, integrity, and availability effects. The CVSS 4.0 score of 2.1 reflects a narrow blast radius with no subsequent system compromise, but a publicly available proof-of-concept (E:P) elevates the likelihood of opportunistic exploitation on internet-facing deployments. …
