CVE-2026-56834

PraisonAI dynamic-context artifact tools read arbitrary host files outside artifact storage Summary PraisonAI's Dynamic Context Discovery feature exposes artifact helper tools through ctx.get_tools(): ctx = setup_dynamic_context() agent = Agent( instructions="You are a data analyst.", tools=ctx.get_tools(), hooks=[ctx.get_middleware()], ) The official documentation describes these helpers as a way for the agent to explore large tool-output artifacts that were queued by the middleware: - large tool outputs are saved as artifacts; - the agent receives compact artifact references; and - the agent uses artifact_tail and artifact_grep to explore that data. The implemented artifact tools do not enforce that the supplied artifact_path is an artifact created by the configured store or that it lives under the configured artifact base directory. Instead, artifact_head, artifact_tail, artifact_grep, and artifact_chunk wrap the caller-supplied path directly into an ArtifactRef and then read it from the host filesystem. As a result, any prompt/user/tool-caller that can influence those tool arguments can read files readable by the PraisonAI process, such as project .env files, cloud credentials, SSH keys, source files, or other local data.
