EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.0 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 94% 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.464, GET /api/v1/deployments/{uuid} in DeployController.php retrieves deployment details without validating that the deployment belongs to the authenticated user's team. Any authenticated API user can read deployment records from other teams by providing a valid deployment UUID. This vulnerability is fixed in 4.0.0-beta.464.
