CVE-2026-11745: Central Dogma: SSH host-key verification permanently disabled in Git mirror (SshGitMirror)

Threat model: An on-path attacker on the corporate network — ARP spoofing on the LAN, internal DNS poisoning, malicious internal DNS overriding github.com or the configured internal git hostname, BGP hijack, sidecar/CNI compromise in Kubernetes, or any process able to answer TCP on the resolved IP. No Central Dogma account required; only network position.

1. Direction LOCAL_TO_REMOTE: the attacker impersonating the remote git server receives the entire mirrored repository contents over the SSH session. Central Dogma is a configuration store, so this typically exfiltrates DB credentials, third-party API keys, certificates, feature flags, and any other secret configuration committed to mirrored repositories.
2. Direction REMOTE_TO_LOCAL: the attacker can serve arbitrary commits which Central Dogma materializes into the local repo and then broadcasts to every subscribing microservice via the watch API. This is a supply-chain root-of-trust compromise across all downstream services consuming Central Dogma configuration.
3. Credential theft chain with finding H2 (mirror credentials are not bound to a hostname): an SSH key or access token configured for github.com can be captured by the attacker’s fake server and replayed against the real upstream, extending impact beyond Central Dogma itself.

Scope is Changed (CVSS) because exploitation alters trust assumptions of every downstream client of Central Dogma, not just Central Dogma itself.
