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. Check out the EPSS documentation for more details.

langchain-experimental is a package that holds experimental LangChain code, intended for research and experimental uses.
Affected versions of this package are vulnerable to Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') via the PALChain
in the python exec
method. An attacker can bypass the fix for CVE-2023-36258 and execute arbitrary code by exploiting this vulnerability.
