Backstage is an open framework for building developer portals. A malicious actor with authenticated access to a Backstage instance with the catalog backend plugin installed is able to interrupt the service using a specially crafted query to the catalog API. This has been fixed in the 1.26.0 release of the @backstage/plugin-catalog-backend. All users are advised to upgrade. There are no known workarounds for this vulnerability.
Weakness
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
