The accompanying lines disable the `known_hosts` and `~/.ssh/config` fallbacks, and a repo-wide search confirms that no host-key pinning mechanism (no `acceptedHostKeys`, `knownHosts`, `KnownHostsServerKeyVerifier`, `StaticServerKeyVerifier`, or `RequiredServerKeyVerifier`) exists anywhere in `server-mirror-git/`. Operators have no opt-in way to enable verification. Every outbound mirror connection blindly trusts whatever host key the remote presents.\n\n## Evidence\n\nFile: `server-mirror-git/src/main/java/com/linecorp/centraldogma/server/internal/mirror/SshGitMirror.java`\nLines 143-160 (especially 149) on branch `main` @ commit `d64a5151`:\n\n```java\nprivate SshClient createSshClient() {\n    final ClientBuilder builder = ClientBuilder.builder();\n    // Do not use local file system.\n    builder.hostConfigEntryResolver(HostConfigEntryResolver.EMPTY);   // line 146\n    builder.fileSystemFactory(NoneFileSystemFactory.INSTANCE);        // line 147\n    // Do not verify the server key.","public_affected_ranges":["< 0.84.0"]}],"null_published_at":"2026-11-04T10:04:27.929Z","source_updated_at":"2026-09-11T20:45:51.000Z","source_disclosed_at":"2026-09-11T20:45:50.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-01T22:54:05.264Z"}],"next_cursor":null,"snapshot_revision":"42594"}
