CVE-2026-62283
Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. Nezha versions 1.14.13 through 1.14.14 and 2.0.0 through 2.0.9 do not bind stream identifiers created by CreateStream in service/rpc/io_stream.go to their creating user, and `GET /ws/terminal/:id` and `GET /ws/file/:id` only check whether the supplied UUID exists. An authenticated RoleMember who obtains a live stream UUID from logs, browser history, referer data, or telemetry can attach to another user's terminal or file-manager session, read and write target-server files, and execute shell commands. This issue is fixed in version 2.0.10.
