CVE-2026-47828

Severity CVSS v4.0:
HIGH
Type:
Unavailable / Other
Publication date:

Description

During bosh create-env and bosh delete-env, the CLI uploads compiled CPI packages and rendered job templates to the new VM&amp;#39;s DAV blobstore over HTTPS without verifying the server certificate, even though a CA certificate for that endpoint is available in the installation manifest. A network attacker can terminate the TLS connection, harvest the Basic-auth credentials, and read the rendered-templates archive containing every bootstrap secret for the new BOSH Director, then replay the credentials against the real VM&amp;#39;s agent for root code execution.<br /> Affected versions: bosh-cli versions prior to v7.10.4.
