Findings

L1

identical on amd64, arm64 — one table describes both

CVE Sev CVSS Affects Description
CVE-2026-40228 ↗ L 3.3 systemd In systemd 259, systemd-journald can send ANSI escape sequences to the terminals of arbitrary users when a "logger -p emerg" command is executed, if ForwardToWall=yes is set.

These are the findings of procps, which ships every tool in this project. kapsl reports and gates; it never edits an image to clear a finding.

Composition

default nothing — stands alone
runtime none — self-contained
composes not used as a runtime

Some tools are only useful composed: a pip-installed CLI needs python as its runtime, bash pulls in coreutils. kapsl resolves that for you — -e git,python:flake8 composes explicitly.
