SUSE update for helm

1) Input validation error

EUVDB-ID: #VU106253

Risk: Medium

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2025-22870

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to alter application's behavior.

The vulnerability exists due to insufficient validation of an IPv6 zone ID as a hostname component, when matching hosts against proxy patterns. For instance the NO_PROXY environment variable is set to "*.example.com", a request to "[::1%25.example.com]:80` will incorrectly match and not be proxied. A remote attacker can alter application behavior and potentially  gain access to sensitive information or functionality.

Mitigation

Update the affected package helm to the latest version.
