libcurl 8.16.0 < 8.21.0 WebSocket Auto-PONG Memory Exhaustion (CVE-2026-11586)

The version of libcurl installed on the remote host is 8.16.0 prior to 8.21.0. It is, therefore, affected by a denial of service vulnerability: - By default, curl automatically responds to WebSocket PING frames. Because curl lacks an upper bound on memory allocation for unacknowledged frames, a...

GHSA-CGWC-PV48-FHJ5 python-engineio has unbound thread allocation that can cause denial of service

Impact An attacker can cause the creation of unnecessary background threads in the python-engineio server by exploiting the heartbeat mechanism, which launches a thread when a new connection is received, and when the client sends a PONG packet. Note: this issue primarily affects synchronous...

CURL-CVE-2026-11586 WS Auto-PONG memory exhaustion

By default, curl automatically responds to WebSocket PING frames. Because curl lacks an upper bound on memory allocation for unacknowledged frames, a malicious server can exhaust all available memory by flooding curl with rapid, sequential PING messages...

curl: CVE-2026-11586: WS Auto-PONG memory exhaustion

Summary: TL;DR: a remote WebSocket peer can make default curl/libcurl grow memory until timeout or OOM by sending legal PING frames while refusing to read the client's automatic PONGs. curl automatically replies to each received WebSocket PING with a PONG unless CURLWSNOAUTOPONG is set. In...

curl: WebSocket Logic Error: Control Frame (PING/PONG) Starvation causes Connection Drop (DoS) during large transfers

Summary: I have discovered a logic flaw in lib/ws.c regarding the handling of WebSocket Control Frames PING/PONG. According to RFC 6455, Control Frames should be processed as soon as possible, even in the middle of fragmented data frames, to maintain connection state Keep-Alive. However, libcurl...
