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

Description Conform, a type-safe form validation library, allows the parsing of nested objects in the form of object.property. Due to an improper implementation of this feature, an attacker can exploit it to trigger prototype pollution by passing a crafted input to parseWith... functions. Applications that use Conform for server-side validation of form data or URL parameters are affected by this issue.

Recommendations For versions prior to 1.1.1, update to version 1.1.1 to resolve the issue. As a temporary workaround, consider restricting the use of the parseWith... functions until a patch is applied. Avoid using the object.property form for parsing nested objects in affected versions.
