Descrição técnica

ws is an open source WebSocket client and server for Node.js. All versions from 1.1.0 up to (but not including) 5.2.5, from 6.0.0 up to 6.2.4, from 7.0.0 up to 7.5.11, and from 8.0.0 up to 8.21.0 are affected by a memory exhaustion DoS vulnerability. A peer can send a high volume of exceptionally small fragments and data chunks, with modest network traffic, to force the remote peer into allocating and holding structural wrappers that consume far more memory than the default documented message-size limit, leading to process termination due to OOM. This issue has been fixed in versions 5.2.5, 6.2.4, 7.5.11, and 8.21.0.

———IBM API Connect 10.0.8.0 through 10.0.8.12 and 12.1.0.0 through 12.1.1.2 could allow a remote authenticated attacker to cause a denial of service due to uncontrolled resource consumption. Certain requests can cause internal processing to stall, which could make the service unavailable.12h CVE-2026-71397—

———Allocation of Resources Without Limits or Throttling vulnerability in elixir-grpc grpc_server allows unauthenticated attackers to exhaust memory and crash the node via an oversized client-streaming or bidirectional-streaming request body. The streaming read clause of 'Elixir.GRPC.Server.Adapters.Cowboy.Handler':info/3 (grpc_server/lib/grpc/server/adapters/cowboy/handler.ex) never checks the configured max_body_size. Only the unary read path enforces that cap. 'Elixir.GRPC.Server.Adapters.Cowboy':reading_stream/1 (grpc_server/lib/grpc/server/adapters/cowboy.ex) appends every received chunk to its buffer until a complete length-prefixed message arrives. A client can declare a very large message and send it across many small HTTP/2 DATA frames, and the server buffers all of it. This issue affects grpc_server: from 1.0.0 before 1.0.6.20h CVE-2026-591715.9 MÉD

———JSON-java is a reference implementation of a JSON package in Java. From version 20150729 through 20260522, JSONTokener.nextSimpleValue can accumulate unbounded numeric tokens before JSONObject.stringToNumber passes them to BigInteger or BigDecimal conversion without a length limit. An application that parses attacker-controlled JSON or XML through JSONObject, JSONArray, or XML.toJSONObject can spend super-linear CPU time converting a sufficiently long numeric literal, blocking request-handling threads and causing denial of service. Strict mode and keep-strings settings in JSONParserConfiguration do not prevent the affected conversion path. Version 20260719 limits numeric conversion length.20h CVE-2026-1239976.5 MÉD

——0Hisense VIDAA Smart TV firmware V0000.01.00a.P0220 contains an unauthenticated denial-of-service vulnerability in the UPnP/DLNA AVTransport SOAP service that allows LAN-adjacent attackers to freeze the entire television software layer by sending a crafted SetAVTransportURI request on TCP port 38400. Attackers can exploit this flaw without credentials to render the device completely unresponsive to remote control or front-panel input, requiring a physical power cycle to restore functionality.22h CVE-2026-1233567.5 ALT

——0GROBID is machine learning software for extracting information from scholarly documents. Prior to 0.9.1, the unauthenticated /api/modelTraining endpoint calls GrobidRestProcessTraining.trainModel in GrobidRestProcessTraining.java, where each request creates Executors.newFixedThreadPool(1), submits a training task, and leaves the executor running. Repeated requests permanently retain JVM worker threads and can exhaust process or operating-system thread capacity, degrading or stopping request processing. This issue is fixed in version 0.9.1.22h CVE-2026-1237484.3 MÉD

——0A security flaw has been discovered in chenyme grok2api up to 3.1.6. Affected by this vulnerability is the function proxyVoiceWebSocket of the file backend/internal/transport/http/inference/voice_ws_handler.go of the component WebSocket Proxy. The manipulation results in resource consumption. The attack may be launched remotely. Upgrading to version 3.1.7 addresses this issue. The patch is identified as 7ad0f791f0a9eb5a0ddfe38ac4dfcef01e19a6d4. It is suggested to upgrade the affected component.23h
