AI-suggested
Upgrade PySpector to version 0.1.8 or later, where the incomplete blocklist issue in PluginSecurity.validate_plugin_code is fixed. No other official remediation or temporary fixes are documented. Patch status is not explicitly confirmed in the vendor advisory, but the version 0.1.8 release addresses the vulnerability.
Description
PySpector versions prior to 0.1.8 contain an incomplete blocklist in the PluginSecurity.validate_plugin_code function, allowing bypass of input restrictions via unfiltered Python constructs. This can enable an attacker who supplies a malicious plugin file to execute arbitrary code within the PySpector process. The issue is fixed in version 0.1.8.
