SCA: security update for github.com/charmbracelet/soft-serve (GHSA-pchf-49fh-w34r)

critical Tenable Self-Hosted Container Security Plugin ID 436875

Description

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

 - Soft Serve is a self-hostable Git server for the command line. Versions 0.11.2 and below have a critical
 authentication bypass vulnerability that allows an attacker to impersonate any user (including admin) by
 "offering" the victim's public key during the SSH handshake before authenticating with their own valid
 key. This occurs because the user identity is stored in the session context during the "offer" phase and
 is not cleared if that specific authentication attempt fails. This issue has been fixed in version 0.11.3.
 (CVE-2026-24058)
