This critical-severity CVE scores 9.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 67% 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. Prior to 4.0.0-beta.471, terminal websocket bootstrap routes only check authentication and do not enforce terminal authorization, allowing a low-privileged team member to connect to terminal routes and execute commands on team servers. This issue is fixed in version 4.0.0-beta.471.
