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...
