- Severity: CVSS 6.9 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N

## Affected

- ilbers isar: version range not reported

## Description

Isar is an integration system for automated root filesystem generation. In versions 0.11-rc1 and 0.11, defining ISAR_APT_SNAPSHOT_DATE alone does not set the correct timestamp value for security distribution, leading to missed security updates. This issue has been patched via commit 738bcbb.

## What to do
