Threats tagged 'ghsa-3jqr-28gj-8vq4'

Perspective version 5.0.0 and earlier contains a remote code execution vulnerability due to improper neutralization of directives in dynamically evaluated code. Unauthenticated attackers can submit crafted expression strings to the PolarsVirtualServer backend, which unsafely uses Python's eval() function with minimal restrictions. This allows attackers to traverse Python object attributes and invoke subprocess.Popen, resulting in arbitrary command execution within the Perspective host process.
