CVE-2026-76227

CVE-2026-76227 - MEDIUM Severity Vulnerability

Renovate versions from 42.68.1 before 42.96.3 (and from 42.68.1 before 43.4.4), including corresponding Docker images (renovate/renovate, mend/renovate-ce, renovate-ee-server, renovate-ee-worker >=13.3.0 <13.6.0), fail to restrict environment variables to an allowlist when spawning child processes. As a result, child processes (e.g. npm install, postUpgradeTasks, postUpdateOptions) gain full access to all environment variables of the Renovate process, allowing insider or outside attackers to exfiltrate secrets accessible to the Renovate deployment.

CVE-2026-72648

CVE-2026-72648 - MEDIUM Severity Vulnerability

Cleartext Storage of Sensitive Information in an Environment Variable (CWE-526) in Elastic Cloud on Kubernetes (ECK) can lead to information disclosure via Retrieve Embedded Sensitive Data (CAPEC-37). When ECK reconciles a Fleet Server resource that authenticates to Elasticsearch with a service account token, the token is written into the generated workload specification in cleartext rather than being referenced from the Kubernetes Secret that ECK maintains for the other credentials on the same path. Any principal able to read workload specifications in the affected namespace can therefore read a live Elasticsearch credential, even when Kubernetes RBAC does not grant that principal access to Secrets.
