CVE-2026-54319
MEDIUMDaytona: Path traversal in sandbox volume id mounts arbitrary host paths into the sandbox — cross-tenant data access and host escape
Title source: cnaDescription
Daytona is a secure and elastic infrastructure runtime for AI-generated code execution and agent workflows. Prior to 0.186, a sandbox volume reference (volumeId, which may also be a volume name) was forwarded to the runner and used to build the host bind-mount source path without confinement. A reference containing path-traversal sequences could in principle resolve the mount source outside the intended per-volume base directory. This vulnerability is fixed in 0.186.
