VeloCloud Orchestrator operator escalation (CVE-2026-114625)

A remote caller can access privileged functions in affected on-premises VMware SD-WAN Orchestrator deployments. Apply the vendor fix to protect operator functions and the orchestrator host.

Public CVE record · Vendor or publisher advisory · Source and API bundle

cve.now entry.

Eden terminates the HTTP connection to the affected product, evaluates a declarative policy and — in tier 2 — a separately compiled native Rust module under signed module authority, before any byte reaches the application. It does not patch the affected component; the vendor's fixed release remains the durable repair.

Status: live two-tier remediation recorded (marker class; partiality stated) 2026-11-11 on the installed eden-product-release:1.103.0-single lab container (image sha256:809293e1f0b525ac04698d1fa8d7ffdc66cbee1ff690b082ba26b4d050f08416).

The vulnerability

Any authenticated user of the on-prem orchestrator can gain operator privileges (exploited in the wild).

The Eden patch

Tier 1 — declarative policy (blunt, fail-closed): deny on the affected route family — takes the whole surface offline, legitimate calls included.

Tier 2 — native module: gabriel_velocloud_v1, binary SHA-256 8a947cbcd7897c196137a7489eb8979a46d4e2fd953b2347f927a7ff75ef44c5 (source 89c95ba593242ae4e00ab18829a30e1c08c883c077b8cb0ea28bfcf868b16e1c) — refuse operator-privilege markers in portal bodies (bypassable marker class).

Implement the remediation

The commands are operator examples for the recorded scope. Compare fixture routes and software selectors with the intended deployment before use. See deployment prerequisites.

1. Prepare the target. Verify the loaded product and version against the advisory. Use a compatible Eden HTTP interlay and an authenticated operator with Configure permission. Open the deployment example and API instructions. The bundle identifies module gabriel_velocloud_v1 version 1.0.0 and the SDK revision in patch.toml. Run the policy extraction from the adapter directory.
2. Apply the declarative policy. Scope the policy to /portal/rest and descendants (all methods, deny). Set INTERLAY to the target interlay UUID in the authenticated Eden CLI. Run an authenticated GET /api/v1/interlays/{interlay} with X-Eden-Verbose: true. Save its complete current settings object as current-settings.json and retain the prior remediation declaration for recovery. Set IDEMPOTENCY_KEY to a fresh key for this intended mutation.

jq -e '.tier1' deployment.json > remediation.json
jq -e --slurpfile policy remediation.json \
  '.remediation = $policy[0] | {settings: .}' current-settings.json \
  > interlay-update.json
eden api request PATCH "/api/v1/interlays/$INTERLAY" \
  --header "Idempotency-Key:$IDEMPOTENCY_KEY" \
  --body-file interlay-update.json --content-type application/json --confirm

3. Verify the serving policy. Read back the interlay.

eden api request GET "/api/v1/interlays/$INTERLAY" \
  --header 'X-Eden-Verbose:true'

Check that remediation_status.state is ready and both desired and effective SHA-256 values match the intended declaration. Replay the benign and marked requests in the recorded comparison on an isolated target. Check the recorded response and backend outcome for each probe. Use the request and expected-status table in the linked API example alongside the observed comparison. 4. Restore the previous policy. Coordinate the change with any other operator updating this interlay. Read current settings again and merge the saved remediation field into them. If the prior settings had no remediation field, omit it in the replacement. Send the same PATCH with a fresh idempotency key, then read back the intended state. Repeat the verification probes. Keep the affected route isolated if restoring the prior settings reopens exposure.

Native module gabriel_velocloud_v1

1. Prepare the archive. Use the version 1.0.0 bundle for source, target, and build profile. Configure independent host approval for the installed Eden release. Use the authenticated principals required by the native authority contract. Set PATCH_ARCHIVE to the exact schema-2 package and PACKAGE_SHA256 to its expected archive digest. Verify and import it using the same target interlay.

printf '%s  %s\n' "$PACKAGE_SHA256" "$PATCH_ARCHIVE" | sha256sum --check &&
  eden api request PUT "/api/v1/interlays/$INTERLAY/patch-packages/$PACKAGE_SHA256" \
    --body-file "$PATCH_ARCHIVE" \
    --content-type application/vnd.eden.patch-package.v2+tar --confirm

2. Approve and activate. Enroll the publisher key, attest host software inventory, and inspect the configuration returned by import. Obtain independent host approval. Sign the typed statement with the matching SDK. Send the admit action followed by activate for the prepared operation. Use the applicable typed payload for each action in authority-action.json.

eden api request POST "/api/v1/interlays/$INTERLAY/native-authority" \
  --body-file authority-action.json --content-type application/json --confirm

3. Verify the operation. Read the receipt through the same endpoint. Confirm serving_now and the full expected shard acknowledgment. Repeat the report’s benign and marked probes and check the backend observations.
4. Revoke or restore. Send revoke with the exact operation UUID. Mandatory protection can refuse traffic until a compatible operation is approved and activated. Verify the restored receipt and repeat the probes.

Vendor update. Use the advisory to select the fixed release for the installed branch. Reported fixed releases include 5.2.3.18, 6.1.3.10, 6.4.2.12. Follow the vendor’s update instructions and confirm the version actually loaded by the service.

Measured comparison (live, 2026-11-11)

Performance trace (Eden telemetry, live 2026-11-11)

Measured with Eden's built-in request telemetry (gateway.request.baseline spans, read back through /api/v1/analytics/telemetry?signal=traces), not client wall-clock. Latency Eden introduces per remediation arm for this case:

Eden-added latency for the tier-2 remediation: benign requests complete in 350 µs mean (p50 316 µs, p95 486 µs) in-product, module evaluation included. Honest scope: lab fixtures on one host, fresh connection per measured request, warm requests only; module reactivated shards 2/2 with a fresh signed statement per measurement; spans carry the full authority lineage (module SHA-256, operation, publication). Not the EDEN-3640 performance qualification contract.

Tested against: eden-product-release:1.103.0-single (image sha256:809293e1f0b525ac…, build target eden_service_single, tooling revision 81a0724a…). Raw data: module2/telemetry-ab/velocloud-telemetry.json and module2/tier1-ab/velocloud-tier1.json.

Authority lifecycle and negatives

Driven through the full signed lifecycle (module2/evidence/velocloud-module.json): enroll_key (Ed25519 public key), independent-host inventory, inspect, host approve, signed admit (prepared), activate — receipt serving_now: true, applied_shards == expected_shards (2/2). Negatives held: read-only inspect -> 403, tampered statement binding -> 400, flipped signature bit -> 403. revoke failed the interlay closed (503, nothing forwarded, zero backend effects); a fresh host approval plus a newly signed activation restored the module.

Honest scope

The fixture replicates the delivery shape with harmless marker effects; no real vendor component runs here. Bypass variants (encodings, alternate routes, other crafted members) are not bypass-tested and are out of scope; the rule is a lab-grade partial by construction. The vendor's fixed release remains the durable repair.

Cost record (per-CVE ledger)

Decision flow

The diagram sketches the available source’s content decision after input metadata is available. Continue is a module decision; the host and backend still determine final forwarding and effects.

Complete native module source

The complete available source for gabriel_velocloud_v1 is reproduced below from the reviewed repository snapshot. The source SHA-256 is 89c95ba593242ae4e00ab18829a30e1c08c883c077b8cb0ea28bfcf868b16e1c. This identifies the source bytes, rather than independently proving the binary build or the recorded test results. The case’s experiment status and limitations still apply, including any failed import, partial coverage, or withdrawn claim. Original source comments are preserved verbatim.
