DescriptionCVE.org

PraisonAI before 1.6.78 contains a remote code execution vulnerability in CodeAgent._execute_python() that executes LLM-generated Python code without AST validation, import restrictions, or sandbox enforcement. Attackers can influence LLM output through prompt injection to exfiltrate all environment secrets and execute arbitrary code on the host system.

News Critical RCE in PraisonAI CodeAgent before 1.6.78 - CVE-2026-61447 Jul 11, 2026

AnalysisAI

Remote code execution in PraisonAI before 1.6.78 allows attackers to run arbitrary Python on the host by manipulating the LLM that drives the CodeAgent component. Because CodeAgent._execute_python() runs LLM-generated code with no AST validation, import restrictions, or sandbox, an attacker who can shape model output via prompt injection can exfiltrate all environment secrets and gain full control of the agent host. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the target deployment uses PraisonAI's CodeAgent feature (the component containing _execute_python) and that the attacker can influence the LLM's context - i.e. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment All available signals point to genuine high priority rather than an inflated score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker plants injection text in content the agent will process - a web page, uploaded file, or chat message - instructing the model to write Python that reads os.environ and opens a reverse shell. When the CodeAgent generates and calls _execute_python(), the unsandboxed code runs on the host, exfiltrating API keys and giving the attacker command execution. …
Remediation Vendor-released patch: upgrade to PraisonAI 1.6.78 or later, the first fixed release per the GitHub Security Advisory (https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-2xv2-w8cq-5gxw). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours: Inventory all PraisonAI deployments across the infrastructure and determine whether CodeAgent functionality is actively used; disable CodeAgent if operationally feasible. …
