This critical-severity CVE scores 9.9 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 60% 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).

Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. In Coolify versions prior to and including v4.0.0-beta.434, low privileged users are able to see the private key of the root user on the Coolify instance. This allows them to ssh to the server and authenticate as root user, using the private key. As of time of publication, it is unclear if a patch is available.
