AI Analysis
Technical Summary
The polymarket-onchain-plugin npm package in versions 2.1.3, 2.1.4, and 2.1.5 includes malicious code that compromises the host system. Installation or execution of this package can lead to full system compromise, potentially exposing all stored secrets and keys. Due to the nature of the compromise, removal of the package alone is insufficient to ensure system integrity.
Potential Impact
