CVE-2022-21646
Good to know:
Date: January 11, 2022
SpiceDB is a database system for managing security-critical application permissions. Any user making use of a wildcard relationship under the right hand branch of an "exclusion" or within an "intersection" operation will see "Lookup"/"LookupResources" return a resource as "accessible" if it is not accessible by virtue of the inclusion of the wildcard in the intersection or the right side of the exclusion. In "v1.3.0", the wildcard is ignored entirely in lookup's dispatch, resulting in the "banned" wildcard being ignored in the exclusion. Version 1.4.0 contains a patch for this issue. As a workaround, don't make use of wildcards on the right side of intersections or within exclusions.
