Answer in brief
CVE-2023-22466 records a Unknown severity vulnerability in reject_remote_clients Configuration corruption. The current sources do not mark it as known exploited. The current feed maps tokio (crates.io). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

On Windows, configuring a named pipe server with [pipe_mode] will force [ServerOptions]::[reject_remote_clients] as `false`. This drops any intended explicit configuration for the [reject_remote_clients] that may have been set as `true` previously. The default setting of [reject_remote_clients] is normally `true` meaning the default is also overridden as `false`. ## Workarounds Ensure that [pipe_mode] is set first after initializing a [ServerOptions]. For example: ```rust let mut opts = ServerOptions::new(); opts.pipe_mode(PipeMode::Message); opts.reject_remote_clients(true); ``` [ServerOptions]: https://docs.rs/tokio/latest/tokio/net/windows/named_pipe/struct.ServerOptions.html [pipe_mode]: https://docs.rs/tokio/latest/tokio/net/windows/named_pipe/struct.ServerOptions.html#method.pipe_mode [reject_remote_clients]: https://docs.rs/tokio/latest/tokio/net/windows/named_pipe/struct.ServerOptions.html#method.reject_remote_clients
