SpiceDB: LookupResources with Multiple Entrypoints across Different Definitions Can Return Incomplete Results
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.

Description
Impact
If your schema includes the following characteristics:
- You have a permission defined in terms of a union (
+) - That union references the same relation on both sides, but one side arrows to a different permission
Then you might have missing LookupResources results when checking the permission. This only affects LookupResources; other APIs calculate permissionship correctly.
A small concrete example:
relation doer_of_things: user | group#member
permission do_the_thing = doer_of_things + doer_of_things->admin
A CheckPermission on do_the_thing will return the correct permissionship, but a LookupResources on do_the_thing may miss resources.
A Comprehensive Example
If you have a schema with a structure like this:
definition special_user {}
definition user {
relation special_user_mapping: special_user
permission special_user = special_user_mapping
}
definition group {
relation member: user
permission membership = member + member->special_user
}
definition system {
relation viewer: user | group#membership
// This is the problematic permission
permission view = viewer + viewer->special_user
}
And these relationships:
system:somesystem#viewer@group:somegroup#membership
group:somegroup#member@user:someuser1
user:someuser1#special_user_mapping@special_user:specialuser
And you call LookupResources with:
subject_type: user
subject_id: someuser1
permission: view
resource_type: system
You would expect to receive system:somesystem in the results, but you do not.
Note that this only applies to LookupResources; if you CheckPermission for that resource specifically, it will return HasPermission.
Patches
The issue is fixed in v1.47.1. Upgrading to this version will remediate this issue.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/authzed/spicedb, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/authzed/spicedb to 1.47.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9m7r-g8hg-x3vr is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-9m7r-g8hg-x3vr can be triaged on real exposure rather than presence alone.
Tailored to GHSA-9m7r-g8hg-x3vr. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-9m7r-g8hg-x3vr in your dependencies?
O3 Security finds GHSA-9m7r-g8hg-x3vr across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
