CVE-2023-30857 Information

Description

@aedart/support is the support package for Ion a monorepo for JavaScript/TypeScript packages. Prior to version 0.6.1 there is a possible prototype pollution issue for the MetadataRecord when merged with a base class’ metadata object in meta decorator from the @aedart/support package. The likelihood of exploitation is questionable given that a class’s metadata can only be set or altered when the class is decorated via meta(). Furthermore object(s) of sensitive nature would have to be stored as metadata before this can lead to a security impact. The issue has been patched in version 0.6.1.
