Real-World Exposure
github.com/authzed/spicedbReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
Background
Use of an exclusion under an arrow that has multiple resources may resolve to NO_PERMISSION when permission is expected.
For example, given this schema:
definition user {}
definition folder {
relation member: user
relation banned: user
permission view = member - banned
}
definition resource {
relation folder: folder
permission view = folder->view
}
If the resource exists under multiple folders and the user has access to view more than a single folder, SpiceDB may report the user does not have access due to a failure in the exclusion dispatcher to request that all the folders in which the user is a member be returned
Impact
Permission is returned as NO_PERMISSION when PERMISSION is expected on the CheckPermission API.

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 1.33.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-38361 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.
