HTTP Request Smuggling

io.netty, netty-codec-http is vulnerable to HTTP Request Smuggling. The vulnerability is due to the WebSocket V07/V08 handshaker accepting a WebSocket upgrade request without requiring the Connection: Upgrade and Upgrade: websocket headers, which allows an attacker to force an unrecognized protoc...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the aggregation of incoming WebSocket message fragments without any limit on total size or fragment count. An attacker can exhaust server memory and cause a denial of service ...

blaze: Unbounded WebSocket message aggregation in http4s-blaze-server

Summary http4s-blaze-server aggregates the fragments of an incoming WebSocket message with no limit on total size or fragment count. A client that completes a WebSocket handshake can send an unterminated fragmented message and drive unbounded heap growth in the server JVM, resulting in denial of...

@anephenix/hub: Unauthenticated WebSocket RPC Waiter Resource Exhaustion

Summary @anephenix/hub starts a setInterval polling loop for every incoming WebSocket connection to request a client ID via RPC. If the remote client never replies — which requires no authentication or special configuration — the interval and the pending request object are never cleaned up, even...

GHSA-GH4H-34GR-87R7 Budibase: OAuth2 Token Disclosure via Automation Test Results Broadcast to Other Builders

Summary When an SSO-authenticated user tests an automation in the Budibase builder, their OAuth2 access token and refresh token are included in the automation test results. These results are broadcast via WebSocket to all builders connected to the same dev app and stored in an in-memory cache...

Open WebUI: Terminal proxy forwards a spoofable, integrity-unbound user identity to the upstream (X-User-Id header and ws_terminal session_id query injection)

Summary The terminal proxy in backend/openwebui/routers/terminals.py forwards the Open WebUI user's identity to the upstream terminal server / backend coordinator as an authorization claim, with no cryptographic binding to the session that produced it. The forwarded identity is...

User Impersonation

Overview open-webui is an Open WebUI Affected versions of this package are vulnerable to User Impersonation via the wsterminal process. An attacker can gain unauthorized access to another user's terminal session by injecting crafted values into the sessionid parameter, causing the backend to...
