CVE-2026-49848

Name
CVE-2026-49848
Description
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 check_auth userauth branch wrote request-supplied userVariables into the connection state before comparing the supplied password. The writes are append-only and the connection is not closed on a failed compare, so values declared on bad-password attempts persisted on the same WebSocket and carried into a subsequent successful login on that connection. This issue has been patched in version 1.11.1.
