CVE-2026-61446 is a critical security flaw affecting the plugin manager in the praisonaiagents package prior to version 1.6.78.
The vulnerability allows unverified execution of arbitrary Python files located inside auto-discovery directories.
Specifically, the framework checks both project-level and user-home `.praisonai/plugins/` paths during initialization.
When a `.py` file is discovered, the manager passes the file path directly to importlib.util.spec_from_file_location().
It then loads and runs the module using `importlib.util.module_from_spec()` and spec.loader.exec_module().
Crucially, this mechanism operates with zero code signing, integrity verification, or sandboxing protections.
The only validation enforced by the system is checking for a Plugin Name field inside the file docstring.
An attacker capable of writing a file to the target plugin directory can achieve arbitrary code execution.
This file write capability can be realized through vulnerabilities like path traversal or compromised dependencies.
Because the plugin system initializes automatically, no user interaction is required to trigger the payload.
Once loaded, the malicious script executes immediately with full Python access to the host environment.
Furthermore, planted plugins survive application restarts, ensuring persistent code execution on every framework launch.
Attackers can chain this vulnerability with path traversal tools to remotely plant files and compromise the system.
Upgrading the framework package immediately resolves this flaw by introducing proper validation controls.

Showing bash commands and codes related to the blog
from praisonaiagents.plugins.discovery import load_plugin
import tempfile, os
test_dir = tempfile.mkdtemp()
plugin_file = os.path.join(test_dir, 'evil.py')
with open(plugin_file, 'w') as f:
f.write('"""\nPlugin Name: Evil Plugin\nDescription: test\nVersion: 1.0.0\n"""\n'
'PROOF = "CODE_EXECUTED_AT_IMPORT_TIME"\n'
'def create_plugin():\n return {"name": "evil"}\n')
result = load_plugin(plugin_file)
print(f"Result: {result}")
import sys
for name, mod in sys.modules.items():
if 'evil' in name:
print(f"EXPLOIT CONFIRMED: {mod.PROOF}")
Exploit: (Educational Purposes!)
The exploit functions by writing a malicious script into the auto-discovered `.praisonai/plugins/` directory. When the framework invokes `load_plugin()` or initializes its plugin manager, it processes any `.py` file using exec_module(). By defining code at the module import level, execution occurs instantly without requiring function calls, allowing total control over the host environment.
Protection: from this CVE
To protect against CVE-2026-61446, upgrade the `praisonaiagents` library to version 1.6.78 or later. Additionally, enforce strict file permissions on project and user home directories to prevent unauthorized creation or modification of files within the plugin auto-discovery paths.
Impact:
Arbitrary code execution with full Python access to the underlying system.
Zero user interaction required as plugins load automatically during framework startup.
Full persistence across application restarts via planted script files.
Effective combination vectors with path traversal vulnerabilities for remote exploitation.
