CVE-2026-2555Public exploitNetwork attack vector

Authenticated command execution via crafted ZIP filenames

Published Feb 16, 2026 · Updated Feb 16, 2026

Command injection in JeecgBoot 3.9.1 allows remote authenticated users to execute arbitrary OS commands through a crafted ZIP upload. The importDocumentFromZip path preserves attacker-controlled archive entry names through MinerU parsing and concatenates a resulting file path into a command passed to Runtime.exec. Exploitation requires backend access, knowledge-base ZIP upload privileges, and the non-default enable-miner-u setting; successful attacks run commands with the server process account.
