Golang: stdlib: security update to 1.26.9stdlib: security update to 1.27.2

high Tenable Cloud Security Plugin ID 473919

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Historically, we have been rather lax about malformed framing-related headers in our HTTP/2
implementation, as they cannot interfere with HTTP/2 framing. However, this makes it possible for our
HTTP/2 implementation to forward responses containing such headers to an HTTP/1 client when acting as a
reverse proxy. If the HTTP/1 client also does not behave strictly enough, this can result in response
smuggling. (CVE-2026-78660)

Solution

Update the stdlib library and its related packages to version 1.26.9 or later.
