CVE-2026-39305
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedPraisonAI is a multi-agent teams system. Prior to 1.5.113, the Action Orchestrator feature contains a Path Traversal vulnerability that allows an attacker (or compromised agent) to write to arbitrary files outside of the configured workspace directory. By supplying relative path segments (../) in the target path, malicious actions can overwrite sensitive system files or drop executable payloads on the host. This vulnerability is fixed in 1.5.113.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidencePraiseonAI versions prior to 1.5.113 contain a path traversal vulnerability in the Action Orchestrator feature. Attackers can use relative path segments (../) in target file paths to escape the intended workspace directory and write to arbitrary locations on the host filesystem, enabling overwrite of sensitive system files or deployment of malicious payloads.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed PraisonAI versionRun 'pip show praisonai' or check your package manager to find the installed version numberAffected if Version is 4.5.112 or lower
-
Verify Action Orchestrator feature is in useCheck if Action Orchestrator module is imported or configured in your deployment - look for 'action_orchestrator' in config files or imported modulesAffected if Action Orchestrator is enabled or configured in your environment
-
Examine file operation logs for path traversal patternsSearch application logs for '../' sequences or unusual path patterns in file write operations - grep logs for '..%2F' or '../' patternsAffected if Logs contain ../ path sequences in file operation requests
-
Inspect workspace directory configurationReview the workspace base directory setting in your PraisonAI configuration - verify it is not allowing parent directory escapesAffected if Workspace directory is not properly sandboxed or allows directory traversal
Your environment is affected if you are running PraisonAI version 4.5.112 or earlier AND have the Action Orchestrator feature enabled, as this combination allows the path traversal vulnerability to be exploited.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to PraisonAI version 1.5.113 or later. Until then, restrict network access to the Action Orchestrator and monitor for ../ path patterns in file operations.
1.5.113
- Upgrade PraisonAI from version 4.5.112 or earlier to version 1.5.113 or later
- After upgrading, verify the installation was successful by checking the PraisonAI version
