What is CVE-2026-8634?

Crabbox versions before v0.12.0 contain a vulnerability that exposes environment variables to potential attackers with access to a compromised repository. This flaw arises from overly permissive allowlisting of environment variables, enabling attackers to serialize sensitive data such as API tokens and cloud credentials into remote command execution contexts. As a result, this creates pathways for unauthorized access to critical secrets that should remain confidential.
