CVE-2025-49011: SpiceDB checks involving relations with caveats can result in no permission when permission is expected

• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

Description

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.
