Description
Impact
Possible prototype pollution for the MetadataRecord, when merged with a base class' metadata object, in meta decorator from the @aedart/support package.
The likelihood is questionable, given that a class' 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 become a vulnerability.
Patches
Has been patched in version 0.6.1.
NVD 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`.
