GHSA-8g29-8xwr-qmhr @grackle-ai/server JSON.parse lacks try-catch logic in its gRPC Service AdapterConfig Handling
Missing error handling in JSON parsing can crash the gRPC service if the database contains invalid data, causing denial of service.

What is GHSA-8g29-8xwr-qmhr?
GHSA-8g29-8xwr-qmhr is a denial of service vulnerability in @grackle-ai/server, published on 25 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Impact
JSON.parse(env.adapterConfig) is called without error handling in three locations within the gRPC service. While the data originates from the server's own SQLite database and should always be valid JSON, database corruption, migration errors, or unexpected state could cause an unhandled exception that crashes the gRPC handler.
Additionally, the parsed result is cast as Record<string, unknown> and passed to adapter methods without property validation, creating a theoretical prototype pollution surface if the database is compromised.
Affected code:
packages/server/src/grpc-service.ts:415—reconnectOrProvisionhandlerpackages/server/src/grpc-service.ts:482—stopEnvironmenthandlerpackages/server/src/grpc-service.ts:498—destroyEnvironmenthandler
Patches
Fix: Wrap in try-catch and return a meaningful gRPC error:
let config: Record<string, unknown>;
try {
config = JSON.parse(env.adapterConfig) as Record<string, unknown>;
} catch {
throw new ConnectError("Invalid adapter configuration", Code.Internal);
}
Workarounds
Ensure database integrity. Back up the SQLite database regularly.
