CVE-2025-49011 (GCVE-0-2025-49011)

Vulnerability from cvelistv5 – Published: 2025-06-06 17:36 – Updated: 2025-06-06 21:33

Title

SpiceDB checks involving relations with caveats can result in no permission when permission is expected

Summary

SpiceDB is an open source database for storing and querying fine-grained authorization data. Prior to version 1.44.2, on schemas involving arrows with caveats on the arrow’ed relation, when the path to resolve a CheckPermission request involves the evaluation of multiple caveated branches, requests may return a negative response when a positive response is expected. Version 1.44.2 fixes the issue. As a workaround, do not use caveats in the schema over an arrow’ed relation.

GHSA-CWWM-HR97-QFXM

Vulnerability from github – Published: 2025-06-06 21:41 – Updated: 2025-06-10 19:58

Summary

SpiceDB checks involving relations with caveats can result in no permission when permission is expected

Details

Impact

On schemas involving arrows with caveats on the arrow’ed relation, when the path to resolve a CheckPermission request involves the evaluation of multiple caveated branches, requests may return a negative response when a positive response is expected.

For example, given this schema:

definition user {}

definition office {
    relation parent: office
    relation manager: user
    permission read = manager + parent->read
}

definition group {
    relation parent: office
    permission read = parent->read
}

definition document {
    relation owner: group with equals
    permission read = owner->read
}

caveat equals(actual string, required string) {
    actual == required
}

and these relationships:

office:headoffice#manager@user:maria
office:branch1#parent@office:headoffice
group:admins#parent@office:branch1
group:managers#parent@office:headoffice
document:budget#owner@group:admins[equals:{"required":"admin"}]
document:budget#owner@group:managers[equals:{"required":"manager"}]

Permission for 'document:budget#read@user:maria with {"actual" : "admin"}' is returned as NO_PERMISSION when HAS_PERMISSION is the correct answer.

Patches

Upgrade to v1.44.2.

Workarounds

Do not use caveats in your schema over an arrow’ed relation.

Severity

3.7 (Low)
