Starting with version 1.7.0 and prior to versions 1.18.4, 1.20.3, and 1.23.1, when configuring a Windows named pipe server, setting `pipe_mode` will reset `reject_remote_clients` to `false`. If the application has previously configured `reject_remote_clients` to `true`, this effectively undoes the configuration. Remote clients may only access the named pipe if the named pipe's associated path is accessible via a publicly shared folder (SMB). Versions 1.23.1, 1.20.3, and 1.18.4 have been patched. The fix will also be present in all releases starting from version 1.24.0. Named pipes were introduced to Tokio in version 1.7.0, so releases older than 1.7.0 are not affected. As a workaround, ensure that `pipe_mode` is set first after initializing a `ServerOptions`.","state":0,"publishedAt":"2023-01-04T22:15:09.267+00:00","modifiedAt":"2026-06-17T05:35:30.943+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:L","score":5.4,"severity":"MEDIUM"},{"system":"CVSS 3.1 · nvd@nist.gov · Primary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/tokio-rs/tokio/pull/5336","https://github.com/tokio-rs/tokio/releases/tag/tokio-1.23.1","https://github.com/tokio-rs/tokio/security/advisories/GHSA-7rrj-xr53-82p7","https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-createnamedpipea#pipe_reject_remote_clients"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2023-22466","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-665"],"productCriteria":["cpe:2.3:a:tokio:tokio:*:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2023-01-04T22:15:09.267","lastModified":"2026-06-17T05:35:30.943"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
