SCA: security update for github.com/authzed/spicedb (GHSA-4vrg-r928-h5vv)

low Tenable Self-Hosted Container Security Plugin ID 443658

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - SpiceDB is an open source database system for creating and managing security-critical application
 permissions. From 1.34.0 until 1.54.0, SpiceDB can return PERMISSIONSHIP_HAS_PERMISSION instead of
 PERMISSIONSHIP_CONDITIONAL_PERMISSION or PERMISSIONSHIP_NO_PERMISSION because checkRequestToKey() and
 checkRequestToKeyWithCanonical() in internal/dispatch/keys/computed.go omit CheckHints when constructing
 dispatch Check cache keys. The incorrect result requires a permission combining relations with
 intersection or exclusion, a subject reachable through caveated and non-caveated branches, LookupResources
 with a context parameter running concurrently with CheckPermission or CheckBulkPermissions for the same
 resource and subject, and an enabled dispatch result cache. Under these conditions, a result computed for
 one hint set can poison the cache entry used by a semantically different authorization check, allowing
 permission without satisfying the caveat. This issue is fixed in version 1.54.0. (CVE-2026-55866)

Solution

Update the github.com/authzed/spicedb library and its related packages to version 1.54.0 or later.
