Name of the Vulnerable Software and Affected Versions pathval versions prior to 1.1.1

Description The issue is related to prototype pollution, which affects the pathval package. This type of issue can occur when an application does not properly validate user input, allowing an attacker to pollute the prototype of an object, potentially leading to security vulnerabilities.

Recommendations For versions prior to 1.1.1, update to version 1.1.1 or later to resolve the issue. As a temporary workaround, consider implementing input validation to prevent prototype pollution. Restrict access to sensitive functions and variables to minimize the risk of exploitation.
