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.
