CVE-2026-6576Public exploitNetwork attack vector

Authenticated command execution via unfiltered os.popen

Published Apr 19, 2026 · Updated Apr 19, 2026

Command injection in DjangoBlog 2.1.0 allows remote authenticated users to execute OS commands through the WeChat bot interface. CommandHandler passes the supplied command directly to os.popen and reads its output without validation, escaping, or an allowlist. The public bot endpoint requires bot authentication, but rotating source identifiers bypasses its per-source lockout; commands run with the application process's privileges.
