    Allocation of Resources Without Limits or Throttling

    crossbar is a Crossbar.io multi-protocol (WAMP/WebSocket, REST/HTTP, MQTT) application router for microservices.

    Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the onFrameData function in protocol.py, where the maxMessagePayloadSize limit is enforced against the compressed wire size of a permessage-compressed WebSocket frame rather than the uncompressed (inflated) application-level payload. An attacker can send a small compressed WebSocket frame that inflates far beyond the configured limit, bypassing the size check and delivering an oversized payload to the application, which can crash or exhaust resources in the receiving process.

    How to fix Allocation of Resources Without Limits or Throttling?

    Upgrade crossbar to version 26.7.1 or higher.
