CVE-2026-112017 Details
Description
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.
A SQL injection vulnerability has been identified in JeecgBoot versions prior to 3.9.5. This vulnerability allows authenticated attackers to bypass the SqlInjectionUtil keyword blocklist by inserting newline characters into dictionary and online report SQL fragments. The injection can be exploited through endpoints such as /sys/dict/getDictItems, leading to boolean or time-based blind injection. This exploitation allows attackers to extract database contents, including administrator password hashes from the sys_user table.
Users can update to JeecgBoot version 3.9.5 or later, where this vulnerability has been addressed. Instructions for updating can be found in the JeecgBoot release notes.
