EUVD-2026-89541

AiSOC versions 5.1.0 before 12.0.0 contain an authentication bypass vulnerability in the realtime service internal endpoints POST /internal/agent-event and POST /internal/push. Attackers can post arbitrary events with spoofed tenant identifiers to broadcast malicious content over WebSocket and...

CVE-2026-103055

AiSOC versions 7.5.0 before 12.0.0 are vulnerable to an authentication bypass due to the use of a hard-coded constant for JWT verification in the realtime WebSocket and SSE service . This flaw occurs specifically when the AISOC_REALTIME_JWT_SECRET environment variable is not configured. Unauthent...

EUVD-2026-89539

AiSOC versions 7.5.0 before 12.0.0 use a hard-coded constant for JWT verification in the realtime WebSocket and SSE service when the AISOCREALTIMEJWTSECRET environment variable is not set. Unauthenticated attackers can forge subscription tickets with arbitrary tenant identifiers to access...

CVE-2026-51856

In agentscope 1.0.18, 1.0.19, and 1.0.19 when the RealtimeAgent session exposes executepythoncode as an available tool, a remote WebSocket user can prompt the agent to call that tool and run Python code in the service environment. In the validated path, RealtimeAgent.acting forwards the...

undici: undici: Denial of Service via unrequested WebSocket subprotocol

A flaw was found in undici. A remote attacker can exploit this vulnerability by responding with an unrequested WebSocket subprotocol during the opening handshake. This causes the undici WebSocket client to crash the entire Node.js process, leading to a denial of service DoS...

undici vulnerable to Denial of Service via unrequested WebSocket subprotocol

Impact The undici WebSocket client throws an uncaught TypeError during the opening handshake when a server's 101 response includes a Sec-WebSocket-Protocol header that the client never requested. The throw occurs in a queueMicrotask callback with no surrounding try/catch, so it propagates as an...

CVE-2026-102761

NetX Duo's WebSocket client resets the unmasking cursor to the first NXPACKET each time it advances through a chained packet, while the loop's upper bound belongs to the current packet. With the standard contiguous packet-pool layout, a masked server frame split across two packets therefore drive...

CVE-2026-102559

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...

CVE-2026-102560

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...

CVE-2026-102761

The NetX Duo WebSocket client is vulnerable to a memory corruption issue due to an incorrect unmasking cursor reset logic. When processing a chained packet, the client resets the cursor to the first NX_PACKET while the loop's upper bound remains tied to the current packet. In a standard contiguou...

CVE-2026-102557

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...
