CriticalVulnerabilityCVE-2026-115216updated 27 Oct 2026, 12:18 UTC

Eclipse ioFog Operator can be spied on over unencrypted-check connections

The software that manages ioFog devices stops checking whether the servers it talks to are genuine. An attacker sitting on the network path could pose as the real server and steal login secrets.

How the attack works simplified

  1. 1On-path positionAttacker sits between operator and server
  2. 2Fake certificateAny certificate is accepted without checking
  3. 3Credentials capturedClient secret or admin password is stolen
  4. 4Token reusedStored access token is used for Controller calls
  5. ResultAttacker controls Controller API access

What happened

In Eclipse ioFog Operator 3.8.0 before 3.9.2, TLS certificate verification is disabled when the operator contacts the Controller API and when logging in to an external OIDC issuer, allowing on-path man-in-the-middle attacks.

Why it is dangerous: An attacker who can intercept traffic can capture the OAuth client secret or the Controller bootstrap admin password, then reuse the access token the operator stores, gaining control over Controller API calls.

Are you affected?

You are affected if you run Eclipse ioFog Operator versions 3.8.0 up to but not including 3.9.2, in external OIDC mode or embedded mode with Controller HTTPS enabled.

Eclipse ioFog Operator 3.8.0 to before 3.9.2

What to do

  1. Upgrade Eclipse ioFog Operator to version 3.9.2 or later
  2. Rotate the OAuth client secret (external mode) or the Controller bootstrap admin password (embedded mode) if the operator ran unpatched on a network where interception was possible
  3. Restrict network paths between the operator and the Controller API and OIDC issuer until upgraded
