Name of the Vulnerable Software and Affected Versions js-ini versions prior to 1.3.0

Description The issue arises when an attacker submits a malicious INI file to an application that uses the parse function to parse it. This can lead to prototype pollution on the application, which can be further exploited depending on the context.

Recommendations For versions prior to 1.3.0, update to version 1.3.0 or later to resolve the issue. As a temporary workaround, consider restricting the use of the parse function to minimize the risk of exploitation. Avoid parsing untrusted INI files until the issue is resolved.
