CVE-2026-108677 Details
Description
JeecgBoot through 3.9.5 contains a missing authorization vulnerability in GET /sys/api/getUserByName that allows low-privileged authenticated users to retrieve any user's stored password value. Attackers can decrypt the AES-CBC protected response using the hard-coded key exposed by /sys/getEncryptedString to obtain administrators' password ciphertexts for offline guessing.
A missing authorization vulnerability has been identified in JeecgBoot versions through 3.9.5. The issue resides in the GET endpoint /sys/api/getUserByName, where low-privileged authenticated users can access any user's stored password. This vulnerability arises because the endpoint lacks proper authorization checks, allowing unauthorized access to sensitive information. Additionally, the retrieved passwords are encrypted using AES-CBC, but can be decrypted with a hard-coded key available from the /sys/getEncryptedString endpoint, enabling offline password guessing attacks, particularly against administrator accounts.
