CVE-2026-115216
Published on October 27, 2026
Eclipse ioFog Operator disables TLS certificate verification when sending Controller and OIDC credentials
In Eclipse ioFog Operator versions 3.8.0 before 3.9.2, TLS certificate verification is disabled when the operator contacts the Controller API and when it logs in to an external OIDC issuer. An on-path attacker can present any certificate, capture the OAuth client secret (external mode) or the Controller bootstrap admin password (embedded mode with Controller HTTPS enabled), and supply the access token the operator stores for later Controller API calls. v3.8 removed Keycloak. The exposed credential is not a Keycloak realm-admin secret.
Vulnerability Analysis
CVE-2026-115216 is exploitable with network access, and does not require authorization privileges or user interaction. This vulnerability is considered to have a low attack complexity. Public availability of a proof of concept (POC) exploit exists for CVE-2026-115216. The potential impact of an exploit of this vulnerability is considered to have no impact on confidentiality and integrity and availability.
Weakness Type
Improper Certificate Validation
The software does not validate, or incorrectly validates, a certificate. When a certificate is invalid or malicious, it might allow an attacker to spoof a trusted entity by interfering in the communication path between the host and client. The software might connect to a malicious host while believing it is a trusted host, or the software might be deceived into accepting spoofed data that appears to originate from a trusted host.
Affected Versions
Eclipse Foundation Eclipse ioFog:- Version 3.8.0 and below 3.9.2 is affected.
