AI risk analysis

Summary: The flaw allows any authenticated user to modify protected records without proper authorization checks, leading to potential data corruption or service disruption.
Exploitability: Exploitation is relatively easy as it requires an authenticated session but no additional permissions beyond config type access.
Blast radius: If exploited, this could lead to significant damage by allowing unauthorized changes to critical application state.
Prioritized remediation: Update to version 10.1.1 or apply the fix manually to ensure proper permission checks are enforced.

NVD description

deepstream is a server that allows clients and backend services to sync data, send messages and make rpcs at scale. From 10.1.0 until 10.1.1, src/services/permission/valve/rules-map.ts omits RECORD_ACTION.PATCH_MULTI from RULES_MAP. When an authenticated user sends a PATCH_MULTI record operation while permission.type is config, getRulesForMessage returns a null rule specification and ConfigPermission.canPerformAction treats the missing specification as an unconditional allow instead of applying RULE_TYPES.WRITE. Any authenticated user can therefore modify arbitrary protected records, corrupt application state, or cause service disruption; deployments using the default permission type none already allow all operations and are not additionally affected. This issue is fixed in version 10.1.1.
