Lifecycle Timeline
2DescriptionCVE.org
PraisonAI before 4.6.78 contains arbitrary file write and command execution vulnerabilities in the AICoder component due to missing path validation and command sanitization in LLM tool calls. Attackers can inject malicious prompts through the chat interface to write files to arbitrary filesystem locations and execute arbitrary shell commands with root privileges.
AnalysisAI
Root-level command execution and arbitrary file write in PraisonAI's AICoder component (all versions before 4.6.78) let an attacker with chat-interface access weaponize LLM tool calls: because file paths are not validated and shell commands are not sanitized, a crafted prompt can write files anywhere on the host and run arbitrary shell commands as root. Reported by VulnCheck and fixed in 4.6.78, this is a CVSS 9.4 (v4.0) flaw with no public exploit identified at time of analysis, though the injection path is trivial to trigger for any user who can reach the chat.
