Path Traversal in praisonaiagents (CVE-2026-61443)
Summary
Path traversal in praisonaiagents (CVE-2026-61443). Confidential information can be exposed externally. Exploitable via script_path. Mitigation: upgrade to 1.6.78 or later.
Original description
The description as published by the source.
Summary
SkillTools.run_skill_script() accepts a script_path parameter and executes it via subprocess.run() without any path containment validation. While FileTools has _validate_path() with traversal detection, SkillTools performs none. An LLM-directed call can execute arbitrary scripts from any filesystem location. The @require_approval decorator can be bypassed via YAML approve: for high-risk tools.
Details
src/praisonai-agents/praisonaiagents/tools/skill_tools.py (lines 69-119):
def run_skill_script(self, script_path: str, ...):
script_path = os.path.expanduser(script_path)
if not os.path.isabs(script_path):
script_path = os.path.join(self._working_directory, script_path)
script_path = os.path.abspath(script_path)
if not os.path.exists(script_path):
return f"Error: Script not found at {script_path}"
# No path traversal check, no containment validation
# Directly executes whatever is at that path:
result = subprocess.run(cmd, ...)
By contrast, FileTools._validate_path() (src/praisonai-agents/praisonaiagents/tools/file_tools.py, lines 42-78) properly validates that the resolved path stays within the working directory:
def _validate_path(self, filepath: str) -> str:
# ...
cwd = os.path.abspath(os.getcwd())
if os.path.commonpath([absolute, cwd]) != cwd:
raise ValueError(f"Path traversal detected: {filepath} escapes workspace {cwd}")
