CVE-2022-21646

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.

CVE-2021-41767

Apache Guacamole 1.3.0 and older may incorrectly include a private tunnel identifier in the non-private details of some REST responses. This may allow an authenticated user who already has permission to access a particular connection to read from or interact with another user’s active use of that same connection.

CVE-2021-46283

nf_tables_newset in net/netfilter/nf_tables_api.c in the Linux kernel before 5.12.13 allows local users to cause a denial of service (NULL pointer dereference and general protection fault) because of the missing initialization for nft_set_elem_expr_alloc. A local user can set a netfilter table expression in their own namespace.
