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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-62283)\n\nAffected packages:\n\n- `github.com/nezhahq/nezha >= 1.14.13, <= 1.14.14`\n- `github.com/nezhahq/nezha >= 2.0.0, < 2.0.10`\n\nPatched in:\n\n- `github.com/nezhahq/nezha 2.0.10`\n\nSource: https://osv.dev/vulnerability/GHSA-q6xx-5vr8-p898","depth":"midnight","depthScore":55,"depthScoreParts":{"impact":54.5,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
