CVE-2026-41206 Details
Description
PySpector is a static analysis security testing (SAST) Framework engineered for modern Python development workflows. The plugin security validator in PySpector uses AST-based static analysis to prevent dangerous code from being loaded as plugins. Prior to version 0.1.8, the blocklist implemented in `PluginSecurity.validate_plugin_code` is incomplete and can be bypassed using several Python constructs that are not checked. An attacker who can supply a plugin file can achieve arbitrary code execution within the PySpector process when that plugin is installed and executed. Version 0.1.8 fixes the issue.
A vulnerability exists in PySpector, a static analysis security testing framework for Python, prior to version 0.1.8. The issue arises in the plugin security validator, which uses abstract syntax tree (AST) analysis to block dangerous code from being loaded as plugins. However, the blocklist is incomplete and can be bypassed with certain Python constructs that are not monitored. This allows an attacker to execute arbitrary code within the PySpector process by supplying a malicious plugin file that is installed and run.
Users should update to PySpector version 0.1.8 or later, where this vulnerability has been fixed.
