CVE-2026-82955: CWE-295 Improper certificate validation in Eclipse Foundation Eclipse aeriOS
Description
In the current development version of Eclipse aeriOS, which has not yet had an official release, the KrakenD instance included in the API Gateway component had the disable_jwk_security parameter hard-coded to true, with no option to override it through the Helm chart configuration. This setting disables TLS certificate verification when KrakenD retrieves the JSON Web Key Set (JWKS) used to validate bearer tokens, potentially allowing an attacker with the ability to intercept this communication to provide a malicious JWKS and compromise token validation. The issue has been addressed by making the parameter configurable through the boolean Helm value krakend.config.disableJwkSecurity and setting its default value to false, ensuring that TLS certificate verification is enabled by default.

Technical Analysis
In Eclipse aeriOS development builds, the KrakenD API Gateway component had a hard-coded setting (disable_jwk_security=true) that disabled TLS certificate validation when fetching JWKS for bearer token validation. This improper certificate validation (CWE-295) could allow an attacker capable of intercepting network traffic to inject a malicious JWKS, undermining token validation security. The vulnerability has been addressed by introducing a Helm chart boolean configuration (krakend.config.disableJwkSecurity) with a default value of false, restoring TLS certificate verification by default.
Potential Impact
An attacker with network interception capabilities could exploit this vulnerability to supply a malicious JWKS, potentially compromising the validation of bearer tokens and allowing unauthorized access or privilege escalation. The CVSS 4.0 score of 9 (critical) reflects the high impact and network attack vector with no user interaction required.
Mitigation Recommendations
The vulnerability has been fixed by making the disable_jwk_security parameter configurable and setting its default to false, enabling TLS certificate verification by default. Users should upgrade to the fixed development version or apply the configuration change to ensure TLS verification is enabled. Since this is a development version with no official release yet, users should monitor the vendor advisory for official releases and patches.
