A vulnerability was found in getzep graphiti up to 0.30.2. Affected is an unknown function of the file server/graph_service/main.py of the component REST API. The manipulation results in improper authentication. The attack can be launched remotely. The pull request to fix this issue awaits acceptance.
AnalysisAI
The graphiti FastAPI-based graph memory REST API (getzep/graphiti ≤ 0.30.2) shipped its ingest and retrieve routers with zero authentication - no API key, no token, no session check of any kind. Any unauthenticated remote caller with network access to the service can read stored knowledge-graph episodes or inject and overwrite graph data by sending ordinary HTTP requests. …

Vulnerability AssessmentAI
| Exploitation | The graphiti server component (`server/graph_service/`) must be network-reachable from the attacker - internet exposure is not required, but any network path (cloud VPC, internal LAN) to the listening port suffices. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L) accurately reflects the technical reality: network-reachable with no prerequisites, but limited to the service's data plane - graph episode reads and writes - with no code execution or OS-level access. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the fix from GitHub PR #1739 (https://github.com/getzep/graphiti/pull/1739) once merged and a patched release is published - no confirmed patched release version was available at time of filing. … Detailed patch versions, workarounds, and compensating controls in full report. |
