CVE-2026-56833: PYSEC-2026-3499 - PraisonAI Dynamic Context history and terminal tools read files outside configured storage via path traversal

CVE-2026-56833 · Severity: low · CVSS 3.1 · Published 2026-07-23

Technologies: praisonai (PyPI). Vendors: PyPI, PraisonAI.

Executive brief

PraisonAI's Dynamic Context module manages agent history and terminal logs on disk. A path traversal vulnerability allows lower-privileged users or prompts calling the history and terminal tools to read arbitrary .jsonl and .log files outside the configured storage directory by manipulating run_id and agent_id parameters. An attacker with access to these tools could disclose sensitive data stored elsewhere on the system.

Technical details

The vulnerability exists in HistoryStore._get_history_path() and TerminalLogger._get_log_path() in src/praisonai/praisonai/context/history_store.py and src/praisonai/praisonai/context/terminal_logger.py. These functions construct filesystem paths by joining user-controlled run_id and agent_id parameters without validating that the resolved path remains under the configured base_dir. An attacker can pass an absolute path for run_id or use .. sequences in agent_id to escape the base directory and read files like /etc/passwd or other sensitive .jsonl/.log files. The tools history_tail(), history_get(), history_search(), terminal_tail(), terminal_grep(), and terminal_commands() pass caller-supplied run_id and agent_id directly to these path functions without allowlist validation or relative_to() checks. A patch is available in version 4.6.59 and later.
