CVE-2026-111617: Missing Authentication for Critical Function

WHartTest through 2.8.1 contains a missing authentication vulnerability that allows unauthenticated attackers to connect to the /ws/ui/web/ and /ws/ui/actuator/ WebSocket endpoints because UiAutomationConsumer accepts every connection. Attackers can register an actuator with a client-supplied id ...

Red Hat: CVE-2026-111373: freerdp: FreeRDP: Denial of Service via zero-length WebSocket ping

FreeRDP before 3.32.0 contains a NULL pointer dereference vulnerability in the websocket transport that allows a malicious gateway to crash clients by sending zero-length pings. When the payload length is zero, websocketreplypong passes a nullptr stream to websocketreplyclose, triggering an...

Allocation of Resources Without Limits or Throttling

Overview undici is an An HTTP/1.1 client, written from scratch for Node.js Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via unbounded automatic PONG write queuing in the WebSocket ByteParser receiver. A remote attacker can send a flood o...

CVE-2026-109932

A flaw was found in undici. A malicious or compromised WebSocket server can trigger a Denial of Service DoS by repeatedly sending small PING messages while refusing to read the client's automated replies. Because the client ignores flow-control signals when writing responses to the network socket...

Important: Red Hat Security Advisory: libsoup3 security update

An update for libsoup3 is now available for Red Hat Enterprise Linux 10. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from...

libsoup: libsoup: Heap buffer overflow during outgoing permessage-deflate buffer growth

A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow...

libsoup: libsoup: Heap buffer overflow from WebSocket Pong signal type confusion

A flaw was found in libsoup. When handling an incoming WebSocket Pong frame, SoupWebsocketConnection emitted the ::pong signal with a GByteArray pointer even though the signal is declared to pass a GBytes. Applications connecting a handler that follows the documented GBytes API can trigger heap...

libsoup: libsoup: Heap buffer overflow during WebSocket receive-buffer growth

A flaw was found in libsoup. When max-incoming-payload-size is unlimited 0, SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data...

libsoup: libsoup: Heap buffer overflow during WebSocket client-frame masking

A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow...

libsoup: libsoup: Heap buffer overflow during WebSocket message reassembly

A flaw was found in libsoup. When reassembling fragmented WebSocket messages into a GByteArray, libsoup did not adequately cap total message size against the limits of the underlying buffer type. A remote peer could send fragments that caused size truncation while the implementation still used th...

Astra Linux – Vulnerability in libvncserver

It was discovered that the websockets.c file in LibVNCServer prior to version 0.9.12 did not properly decode certain WebSocket frames. A malicious attacker could exploit this by sending specially crafted WebSocket frames to a server, resulting in a heap-based buffer overflow...
