Echo: golang.org/x/crypto: security update to 0.55.0

high Tenable Self-Hosted Container Security Plugin ID 465682

Description

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

 - The source-address critical option in the Permissions returned by an authentication callback was only
 enforced for the PublicKeyCallback and VerifiedPublicKeyCallback paths, extending the fix for
 CVE-2026-46595. Permissions returned by the PasswordCallback, KeyboardInteractiveCallback,
 NoClientAuthCallback, and GSSAPIWithMICConfig.AllowLogin callbacks were not validated against the client's
 remote address, so a source-address restriction set by those callbacks was silently ignored. The check is
 now applied to the Permissions returned by any authentication callback. (CVE-2026-56854)

Solution

Update the golang.org/x/crypto library and its related packages to version 0.55.0 or later.
