CVE-2026-112017: JeecgBoot before 3.9.5 SQL Injection via SqlInjectionUtil Newline Bypass
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.
