Vulnerability in praisonaiagents (CVE-2026-40117)
Summary
Vulnerability in praisonaiagents (CVE-2026-40117). Confidential information can be exposed externally. Exploitable via skill_tools.py. Mitigation: upgrade to 1.5.128 or later.
Original description
The description as published by the source.
Summary
read_skill_file() in skill_tools.py allows reading arbitrary files from the filesystem by accepting an unrestricted skill_path parameter. Unlike file_tools.read_file which enforces workspace boundary confinement, and unlike run_skill_script which requires critical-level approval, read_skill_file has neither protection. An agent influenced by prompt injection can exfiltrate sensitive files without triggering any approval prompt.
Details
The vulnerability is a missing authorization check in read_skill_file() at src/praisonai-agents/praisonaiagents/tools/skill_tools.py:128.
The function's path validation on line 163 only ensures file_path doesn't escape skill_path via directory traversal:
# skill_tools.py:128-170
def read_skill_file(self, skill_path: str, file_path: str, encoding: str = 'utf-8') -> str:
# ...
skill_path = os.path.expanduser(skill_path) # line 147
if not os.path.isabs(skill_path):
skill_path = os.path.join(self._working_directory, skill_path)
skill_path = os.path.abspath(skill_path) # line 150
# ... existence checks ...
full_path = os.path.join(skill_path, file_path) # line 159
full_path = os.path.abspath(full_path) # line 160
# Security check: ensure file is within skill directory
if not full_path.startswith(skill_path): # line 163
return f"Error: Path traversal detected..."
with open(full_path, 'r', encoding=encoding…
