AI Analysis
Technical Summary
The polymarket-onchain-plugin npm package versions =2.1.3, =2.1.4, and =2.1.5 have been identified as containing malicious code. Installation or execution of these versions results in a full compromise of the affected computer, potentially allowing an attacker to gain control and access to sensitive information such as stored secrets and keys. Due to the nature of the compromise, simply uninstalling the package does not guarantee removal of all malicious components. This threat is cataloged under MAL-2026-6864 and GHSA-29mh-pwqh-6586 with no CVSS score assigned.
Potential Impact
Systems with the affected versions of polymarket-onchain-plugin installed are fully compromised, risking exposure and theft of all secrets and keys stored on the system. The attacker may have persistent control beyond the presence of the malicious package itself, leading to a severe security breach.
Mitigation Recommendations
Remove the polymarket-onchain-plugin package versions 2.1.3, 2.1.4, and 2.1.5 immediately. Rotate all secrets and keys from a different, uncompromised system to prevent unauthorized access. Because full control of the system may have been granted to an attacker, consider rebuilding or thoroughly cleaning the affected systems. No official patch or fix is currently available; monitor vendor advisories for updates.
