Technical details

The vulnerability is an authorization bypass (CWE-863) in the StreamSource forceDelete API endpoint. The component performs no authorization checks before allowing deletion operations, meaning any authenticated user—regardless of their intended permissions—can logically delete all stream sources. The attack vector is network-based and requires authentication but no special privileges. An attacker with valid credentials can invoke the vulnerable endpoint to remove critical stream source configurations, impacting data collection and integration workflows. The issue is resolved in Apache InLong 2.4.0 via pull request #12145.
