Ignored sandbox allows attacker-influenced arbitrary command execution with no auth or interaction modeled, yielding full confidentiality, integrity, and availability impact; scope unchanged as the OS is the sandbox's own host.

Lifecycle Timeline
3DescriptionCVE.org
PraisonAI before 4.6.78 contains an unenforced security policy vulnerability in the default Subprocess Sandbox backend where blocked_commands, blocked_paths, blocked_imports, allow_subprocess, and allow_file_write restrictions are completely ignored. Attackers can execute arbitrary subprocess commands, read sensitive files, and perform destructive operations despite explicit security policy configuration.
AnalysisAI
Security-policy bypass in PraisonAI before 4.6.78 renders the default Subprocess Sandbox backend inert, so administrator-defined blocked_commands, blocked_paths, blocked_imports, allow_subprocess, and allow_file_write restrictions are silently ignored. Any actor able to feed instructions into a PraisonAI agent can execute arbitrary subprocess commands, read sensitive files, and perform destructive file operations even though an explicit deny policy is configured. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the deployment uses the default Subprocess Sandbox backend and that an attacker can influence the commands/tasks a PraisonAI agent executes (e.g., via a user-facing agent interface or untrusted content the agent processes). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are moderately strong but partly conflicting. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An application built on PraisonAI exposes an agent endpoint and configures the Subprocess Sandbox with blocked_commands including 'rm' and allow_subprocess set to deny, assuming it is protected. An attacker submits a task that induces the agent to invoke a shell command; because the policy is never checked, the command runs and the attacker reads credentials from the filesystem or deletes data. … |
| Remediation | Vendor-released patch: upgrade PraisonAI to version 4.6.78 or later, which restores enforcement of the sandbox policy; see the advisory at https://github.com/MervinPraison/PraisonAI/security/advisories/GHSA-5r6c-gj4g-r697. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all PraisonAI deployments, identify installed versions, and document exposure scope-specifically which systems are running versions before 4.6.78 and whether sensitive data or critical infrastructure is accessible through affected agents. …
