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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-639","CWE-862"],"references":["https://github.com/nezhahq/nezha/commit/6661d6a7fc1c269f55c7f4e775082ad23fbe0f54","https://github.com/nezhahq/nezha/releases/tag/v2.0.10","https://github.com/nezhahq/nezha/security/advisories/GHSA-q6xx-5vr8-p898"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:38.260478770+00:00"},"epss":{"cve":"CVE-2026-62283","score":0.00551,"percentile":0.45773,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-q6xx-5vr8-p898","url":"https://osv.dev/vulnerability/GHSA-q6xx-5vr8-p898","summary":"Nezha vulnerable to cross-tenant terminal/file-manager session hijack via WebSocket stream UUID without ownership check","modified":"2026-08-22T11:55:38.642875741Z","packages":[{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":[">=1.14.13 <=1.14.14"],"fixed":[]},{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":[">=2.0.0 <2.0.10"],"fixed":["2.0.10"]}]},{"id":"GO-2026-5821","url":"https://osv.dev/vulnerability/GO-2026-5821","summary":"Nezha vulnerable to cross-tenant terminal/file-manager session hijack via WebSocket stream UUID without ownership check in github.com/nezhahq/nezha","modified":"2026-08-22T11:55:38.642875741Z","packages":[{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":[">=1.14.13"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
