CVE-2026-41206: PySpector has a Plugin Code Execution Bypass via Incomplete Static Analysis in PluginSecurity.validate_plugin_code
(updated )
The plugin security validator in PySpector uses AST-based static analysis to prevent dangerous code from being loaded as plugins. 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.
