CVE-2026-84736: CWE-295 Improper certificate validation in Eclipse Foundation Eclipse aeriOS
Description
In the current development version of Eclipse aeriOS, for which no official release has yet been published, the Federator component disables TLS certificate validation for outbound HTTPS connections by default. When the TLS_CERTIFICATE_VALIDATION environment variable is unset or set to false, the component configures its HTTP transport to skip TLS certificate verification. As a result, an attacker able to intercept network communications between the Federator and external services could impersonate those services and intercept sensitive information transmitted over HTTPS, including OAuth client credentials and bearer tokens. The issue has been addressed by enabling TLS certificate validation by default. The TLS_CERTIFICATE_VALIDATION environment variable is now set to true in the default configuration provided by the Helm chart and Docker Compose deployment.

Technical Analysis
In the current development version of Eclipse aeriOS, the Federator component disables TLS certificate validation for outbound HTTPS connections when the TLS_CERTIFICATE_VALIDATION environment variable is unset or set to false. This improper certificate validation (CWE-295) allows an attacker capable of intercepting network communications to impersonate external services and intercept sensitive information transmitted over HTTPS, including OAuth client credentials and bearer tokens. The vulnerability has been mitigated by enabling TLS certificate validation by default, with the TLS_CERTIFICATE_VALIDATION environment variable set to true in default deployment configurations.
Potential Impact
An attacker who can intercept network traffic between the Federator component and external services may impersonate those services and capture sensitive information such as OAuth client credentials and bearer tokens. This compromises confidentiality and could lead to unauthorized access to protected resources.
Mitigation Recommendations
The issue has been addressed by enabling TLS certificate validation by default. The TLS_CERTIFICATE_VALIDATION environment variable is now set to true in the default Helm chart and Docker Compose deployment configurations. Users should ensure they deploy these updated configurations to enforce proper TLS certificate validation.
