CVE-2026-61445Public exploitNetwork attack vector

File write and command execution via LLM tools

Published Jul 11, 2026 · Updated Jul 11, 2026

Path traversal and command injection in Mervin Praison PraisonAI before 4.6.78 allow remote authenticated users to write files and execute commands. AICoder joins an LLM-supplied absolute path to its working directory, opens it for writing, and passes LLM-generated command text to a subprocess without validation, an allowlist, or a sandbox. Access to the chat interface is required; in root-running Docker deployments, injected prompts can overwrite privileged files and execute commands as root.
