CVE-2024-32866
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 in versions prior to 1.1.1, an attacker can exploit the feature 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 vulnerability. Version 1.1.1 contains a patch for the issue.
