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.","published":"2026-08-21T21:17:01.183","modified":"2026-08-21T21:17:01.183","cvss":{"score":9.9,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/nezhahq/nezha/commit/6661d6a7fc1c269f55c7f4e775082ad23fbe0f54","label":"nezhahq/nezha@6661d6a"},"references":[{"type":"WEB","url":"https://github.com/nezhahq/nezha/commit/6661d6a7fc1c269f55c7f4e775082ad23fbe0f54"},{"type":"WEB","url":"https://github.com/nezhahq/nezha/releases/tag/v2.0.10"},{"type":"WEB","url":"https://github.com/nezhahq/nezha/security/advisories/GHSA-q6xx-5vr8-p898"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-21T21:17:01.183"}}
