CVE-2026-61445 MervinPraison CVE debrief

Who should care

Users of PraisonAI versions before 4.6.78 should prioritize upgrading to the latest version to mitigate the risk of arbitrary file writes and command execution attacks. This involves reviewing current deployments, identifying exposed systems, and applying necessary updates or patches. Additionally, operators and security teams should assess their environments for potential vulnerabilities and implement compensating controls where needed.

Technical summary

The AICoder component in PraisonAI before 4.6.78 lacks proper path validation and command sanitization in LLM tool calls. This oversight enables attackers to inject malicious prompts through the chat interface, potentially leading to arbitrary file writes and command execution with root privileges. The vulnerability is characterized by a CVSS score of 9.4, indicating a critical severity level. Affected product deployments may include PraisonAI instances using the AICoder component, particularly those with exposed chat interfaces or integrations with sensitive systems. Defensive measures should focus on validating user input, restricting access to sensitive areas, and monitoring for suspicious activity.

High

Recommended defensive actions

• Upgrade PraisonAI to version 4.6.78 or later
• Implement input validation and sanitization for LLM tool calls
• Monitor chat interface for suspicious activity
• Restrict access to sensitive filesystem locations
• Regularly review and update AICoder component configurations
