[Obsolete("Skipping subject validation is discouraged and may be removed in a future release. Leave subject validation enabled.")]
public bool SkipSubjectValidation { get; init; }Property Value
Remarks
When set to false (default), subjects are validated to ensure they are not empty
and don't contain whitespace characters (space, tab, CR, LF). This prevents CRLF
protocol injection where a subject containing \r\n could inject arbitrary NATS commands.
When set to true, all subject validation is bypassed for maximum throughput.
Only use this if you fully control all subject strings and can guarantee they never
contain whitespace or CRLF sequences.
This option is obsolete and discouraged. With validation off, a subject that merely
contains a space or tab is split into tokens on the wire: PUB foo bar 5 is read
by the server as subject foo with reply-to bar, and SUB foo bar 1
as subject foo joined to queue group bar. Either way the call is silently
misrouted with no error. Disabling validation also removes the guard against CRLF
protocol injection. The saving is negligible next to the network round trip, so this
is kept only for compatibility and may be removed in a future release.
