CVE-2026-46595 CVE Medium False Positive

ssh: VerifiedPublicKeyCallback Skips Source-Address Validation

This advisory does not affect KrakenD

KrakenD does not implement or expose SSH functionality. The golang.org/x/crypto/ssh package is a transitive dependency but its SSH authentication code paths are never invoked during KrakenD operation. The dependency was upgraded as a precaution.

Addressed through routine dependency maintenance in CE 2.13.6 and EE 2.13.4.

Component

golang.org/x/crypto (SSH)

Disclosed

May 26, 2026

Description

Go’s golang.org/x/crypto/ssh skips source-address certificate validation when a VerifiedPublicKeyCallback is used alongside other callback types. This allows a client connecting from an address not listed in the certificate’s source-address restriction to authenticate successfully.
