CVE-2026-56834 · Severity: high · CVSS 7.5 · Published 2026-10-23

PraisonAI is a multi-agent AI system that allows agents to explore large tool outputs stored as artifacts. A flaw in the artifact helper tools allows an attacker who can influence tool arguments to read arbitrary files on the host system, including environment files, cloud credentials, SSH keys, and source code. The vulnerability affects versions 3.8.1 through 4.6.58.

  ```


## Technical details

The artifact_head, artifact_tail, artifact_grep, and artifact_chunk tools accept user-supplied artifact_path parameters without validating that the path is confined to the configured artifact base directory or that it corresponds to a legitimate artifact. These functions wrap the caller-supplied path directly into an ArtifactRef and read it from the filesystem, bypassing containment checks. An attacker with network access to a PraisonAI agent exposed via ctx.get_tools() can enumerate and read any file readable by the PraisonAI process.
