AI risk analysis

Summary: The flaw allows any authenticated user to modify arbitrary protected records, corrupt application state, or cause service disruption due to missing permission checks.
Exploitability: Exploitation is relatively easy as it requires an authenticated user with permission.type set to config. Precondition is the user must be authenticated and have the ability to send a PATCH_MULTI record operation.
Blast radius: If exploited, the impact could be severe, including arbitrary data modification, application state corruption, or service disruption.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to version 10.1.1 or later.

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.
