The Web-UI sibling at `internal/web/handlers.go:1316-1321` sets `Cache-Control: no-store`, `Pragma: no-cache`, `Expires: 0`, `X-Content-Type-Options: nosniff` — and has a test asserting it. The API path was missed.\n\n## Affected\nAll released versions up to v0.3.0.\n\n## Threat model\nThe endpoint returns a freshly minted X25519 private key inline. Without `no-store`, any intermediary proxy or CDN that caches `200 OK` YAML responses retains the private key for its cache TTL. Same applies to browser disk cache for direct API hits. Combined with the cross-tenant authz advisory (critical), even a corrected authz layer would still leak via cache after fix.\n\n## Suggested fix\nCopy the four headers from the Web sibling:\n\n```go\nw.Header().Set(\"Content-Type\", \"application/yaml; charset=utf-8\")\nw.Header().Set(\"Cache-Control\", \"no-store\")\nw.Header().Set(\"Pragma\", \"no-cache\")\nw.Header().Set(\"Expires\", \"0\")\nw.Header().Set(\"X-Content-Type-Options\", \"nosniff\")\n```\n\nMirrors `internal/web/handlers.go:1316-1321`. Add a parallel test to the existing web-side coverage.\n\n## Suggested patch\n\nVerified locally: `go vet`, `go test","public_affected_ranges":["<= 0.3.1"]}],"null_published_at":"2026-11-07T07:07:39.841Z","source_updated_at":"2026-06-12T18:30:11.000Z","source_disclosed_at":"2026-06-12T18:30:09.000Z","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":"2026-11-06T15:13:13.153Z"}],"next_cursor":null,"snapshot_revision":"42594"}
