CVE-2026-49842: CWE-400: Uncontrolled Resource Consumption in signalwire freeswitchCVE-2026-49842 0 FreeSWITCH is a Software Defined Telecom Stack enabling the digital transformation from proprietary telecom switches to a software implementation that runs on any commodity hardware. Prior to version 1.11.1, mod_verto's WebSocket frame loop intercepts a #-prefixed speed-test protocol (#SPU / #SPB / #SPE) before any authentication check. The declared payload size in #SPU was parsed with atoi() and only rejected non-positive values, so an unauthenticated peer could request up to INT_MAX bytes. The server then wrote roughly size * 10 bytes back during the download phase, on the order of 20 GB per request, yielding strong outbound bandwidth amplification from a short request. This issue has been patched in version 1.11.1. Join the discussion | CVE Database V5 | 06/09/2026, 16:02:58 UTC Added: 06/09/2026, 16:26:03 UTC |
