Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Affected versions of this package are vulnerable to Command Injection via the system.run when allowlist parsing fails to reject command substitution tokens inside double-quoted shell text. An attacker can execute unauthorized commands on the node host by crafting payloads that exploit shell substitution within allowlisted commands.
Note: This is only exploitable if the target uses the macOS node-host execution path, exec approvals are set to allowlist mode, ask mode is set to on-miss or off, and the allowlist contains a benign executable used in a shell wrapper flow.
This vulnerability can be mitigated by setting ask mode to always or setting security mode to deny.
