neotoma has tenant isolation gap in relationship query endpointsGHSA-wrr4-782v-jhwh
GHSA-wrr4-782v-jhwh is a security vulnerability in neotoma. A fix is available for neotoma — see the affected versions and patch details below.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
neotomanpmDescription
Summary
The /list_relationships and /retrieve_graph_neighborhood endpoints call getAuthenticatedUserId (confirming a valid session exists) but do not pass the resolved user ID into the Supabase query as an .eq("user_id", userId) filter. As a result, queries return rows from all users rather than scoping to the authenticated caller's data.
Affected code
/list_relationships (src/actions.ts):
- Calls
getAuthenticatedUserIdbut does not apply.eq("user_id", userId)to the relationships query - Uses
.or()string interpolation for entity ID matching without input validation
/retrieve_graph_neighborhood (src/actions.ts):
- Same pattern: auth resolved, user ID not applied to query filter
Affected versions
v0.13.0
Prerequisites
- A valid authentication token for the Neotoma instance (attacker must have a legitimate account on the same instance)
- A known entity ID belonging to another user (~96 bits of entropy — brute-force not practical)
An unauthenticated caller is rejected at the auth middleware layer. The gap requires a second user account on the instance.
Impact
An authenticated user with a known cross-user entity ID can retrieve relationship edges and graph neighborhood data belonging to another user. No write capability is exposed.
Severity
Low under current conditions — no multi-tenant deployments exist. Escalates to Medium the moment two or more user accounts share an instance.
Remediation
- Add
.eq("user_id", userId)to all Supabase queries in both handlers - Validate entity ID inputs with
isNeotomaEntityIdbefore query construction - Replace
.or()string interpolation with separate scoped.eq()calls
Fix tracked in #365 (list_relationships) and #366 (retrieve_graph_neighborhood). Gate gap tracked in #372.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for neotoma, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update neotoma to 0.14.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-wrr4-782v-jhwh 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.
