From the mailing list:

Hello gophers,

We have just released Go versions 1.24.2 and 1.23.8, minor point releases.
These minor releases include 1 security fixes following the security policy:

- net/http: request smuggling through invalid chunked data
  The net/http package accepted data in the chunked transfer encoding
  containing an invalid chunk-size line terminated by a bare LF.
  When used in conjunction with a server or proxy which incorrectly
  interprets a bare LF in a chunk extension as part of the extension,
  this could permit request smuggling.
  The net/http package now rejects chunk-size lines containing a bare LF.
  Thanks to Jeppe Bonde Weikop for reporting this issue.
  This is CVE-2025-22871 and Go issue https://go.dev/issue/71988.
