CVE-2026-82955
Critical 9.0
In plain English
A critical-severity improper certificate validation in Eclipse aeriOS from Eclipse Foundation. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 8% of all known vulnerabilities).
Official 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.
