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.","state":0,"publishedAt":"2026-08-21T20:21:28.712+00:00","modifiedAt":"2026-08-21T21:42:51.779+00:00","affected":[{"ecosystem":"Vendor product","name":"nezha","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nezhahq\",\n                    \"product\": \"nezha\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.14.13, <= 1.14.14\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 2.0.0, < 2.0.10\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/nezhahq/nezha/security/advisories/GHSA-q6xx-5vr8-p898","https://github.com/nezhahq/nezha/commit/6661d6a7fc1c269f55c7f4e775082ad23fbe0f54","https://github.com/nezhahq/nezha/releases/tag/v2.0.10"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-62283","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-62283","identifiers":["CVE-2026-62283"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
