CVE-2026-124555

JeecgBoot v3.9.2 is vulnerable to Remote command execution. The CodeNode component of the AI Flow module supports Groovy script execution. While the `SecurityCheck` class employs a blacklist mechanism to intercept dangerous calls, the dynamic nature of Groovy allows this blacklist to be completely bypassed through string concatenation and reflection.

An issue in JeecgBoot v.3.9.2 allows a remote attacker to execute arbitrary code via the files Parameter in JeecgBoot AI Chat Module.

A security flaw has been discovered in JeecgBoot 3.9.5, affecting the JimuBI component in the file /jeecg-boot/drag/onlDragDatasetHead/getAllChartData. Manipulation of the params argument results in SQL injection. The exploit has been released to the public and may be used for attacks.

JeecgBoot before 3.9.5 contains an sql injection vulnerability that allows authenticated attackers to bypass the SqlInjectionUtil keyword blocklist by inserting newline characters into dictionary and online report SQL fragments. Attackers can send newline-separated payloads to endpoints like /sys/dict/getDictItems for boolean or time-based blind injection, extracting database contents including administrator password hashes from sys_user.

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysUserController getUserDetailByUserId handler that allows any authenticated user to read other users' details. Low-privileged attackers can supply arbitrary userId values to retrieve real names, usernames, emails, phone numbers, birthdays, employee numbers, department paths and posts.

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysDepartRoleController exportXls handler that allows any authenticated user to export department roles. Low-privileged attackers holding only the default minimal role can call /sys/sysDepartRole/exportXls to download all sys_depart_role records, including role names, codes, descriptions and creating users.

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysCommentController exportXls handler that allows any authenticated user to export all comments. Low-privileged attackers can request /sys/comment/exportXls to download every sys_comment row, including comment text and user ids on records they cannot access.

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysUserController queryChildrenByUsername handler that allows any authenticated user to retrieve other users' account records. Low-privileged attackers can supply arbitrary userId values to obtain names, emails, phone numbers, employee numbers, department assignments, and staff lists of departments those users head.

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysMessageController delete handler that allows low-privileged authenticated users to delete message records. Attackers can send DELETE requests with arbitrary id values to remove any sys_sms row, erasing records of sent notifications without ownership checks.

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysMessageTemplateController delete handler that allows any authenticated user to delete message templates. Low-privileged attackers can obtain template ids from the unguarded list endpoint and delete shipped notification templates, causing system notices and workflow reminders to fail.
