Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.474, the buildHelperImage method in app/Livewire/Settings/Index.php constructs a Docker build command using the dev_helper_version field without shell escaping, allowing an attacker who can set the helper version and trigger the helper image build in a development environment to execute arbitrary commands on the server. This issue is fixed in version 4.0.0-beta.474.
CVE-2026-42148
This low-severity CVE scores 3.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 98% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
