Affected packages
• npm pitboss-ng: < 2.0.0 → fixed in 2.0.0
Description
All versions of `pitboss-ng` are vulnerable to Sandbox Escape leading to Remote Code Execution. The package fails to restrict access to the main context through `this.constructor.constructor` . This may allow attackers to execute arbitrary code in the system. Evaluating the payload `this.constructor.constructor('return process.env')()` prints the contents of `process.env`.
Recommendation
No fix is currently available. Consider using an alternative package until a fix is made available.
