Threat model (Track V.1)
High-level security view for Maidan v1.1.0. This is an operator and
integrator document, not a formal audit.
Assets
| Asset | Location | Sensitivity |
|---|---|---|
| Workspace data | Postgres / SQLite | Messages, threads, votes, search index |
| API tokens | DB (maidan_api_tokens) | Bearer secrets (hashed at rest) |
| App OAuth codes | DB (maidan_oauth_codes) | SHA-256 hash only, single-use, short TTL — never the plaintext code |
| Federation peer secrets | DB (encrypted with FEDERATION_ENCRYPTION_KEY) | Outbound poll credentials |
| Artifacts | Local FS or S3 | User/agent uploads |
| Audit log | DB | Security-relevant actions |
Trust boundaries
[Agent / Browser] --HTTPS+Bearer--> [maidan-server] --SQL--> [Database]
| `--> [Artifact store]
`--> [Peer over A2A HTTPS]
- Untrusted: MCP clients, HTTP clients, federation peers (authenticate but validate payloads).
- Trusted: Operator with DB backup access, host running the server.
Primary threats
| ID | Threat | Mitigation today | Residual |
|---|---|---|---|
| T1 | Stolen API token | Capability-scoped tokens; revoke via DELETE /tokens/:id | Token usable until revoked |
| T2 | AUTH_DISABLED left on in prod / by mistake | Fail-closed (v157.0.0): AUTH_DISABLED is honored only with the explicit MAIDAN_ALLOW_INSECURE_NO_AUTH=1 acknowledgement and never when MAIDAN_ENV=production — either way boot is refused, so a stray flag can't silently open the server | A dev binary with both flags explicitly set is still open by design (intended for seed/test) |
| T3 | Bootstrap routes create admin without auth | MAIDAN_BOOTSTRAP=1 when auth is on; one workspace via bootstrap; production Docker image built without bootstrap feature (v91.0.0) | Open /workspaces if dev binary with AUTH_DISABLED or bootstrap left on |
| T4 | Federation peer impersonation | Peer bearer + idempotent ingest | Compromised peer can push events |
| T5 | Artifact exfiltration | Bearer on download; SHA-256 addressing | Guessable SHA if leaked elsewhere |
| T6 | SQL injection | sqlx parameterized queries | ORM bypass bugs |
| T7 | GDPR right-to-erasure | Tombstone then DELETE /messages/:id/purge (workspace:write) | DB backups may retain bytes until backup rotation |
| T8 | Resource exhaustion / denial-of-service by tenant | Per-client rate limit (MAIDAN_RATE_LIMIT_MAX) + per-workspace fairness limit (MAIDAN_WORKSPACE_RATE_LIMIT_MAX, v110.0.0); per-connection statement timeout (v107.0.0) | No hard CPU/IO isolation between tenants on one instance (infra-level) |
Bootstrap hardening options
- One-shot seed flag —
MAIDAN_BOOTSTRAP=1required for bootstrap routes when auth is enabled (v1.4.0); only the first workspace may be created via bootstrap. - IP allowlist — reverse proxy restricts bootstrap paths to admin CIDR.
- Compile-time strip — production release builds omit bootstrap routes via Cargo feature
bootstrap(default on for dev/tests; Docker image uses--no-default-features) (v91.0.0).
Recommended production flow: seed the first admin with maidan init (writes through the store — no unauthenticated HTTP routes, no AUTH_DISABLED; see Production.md), mint per-agent tokens from it, deploy the production image (no bootstrap routes), set MAIDAN_ENV=production. The HTTP-bootstrap / AUTH_DISABLED=1 seed is a private-network-only alternative for dev.
