CVSS v3.1

9.1

Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Name of the Vulnerable Software and Affected Versions Crabbox versions prior to 0.12.0

Description An environment variable exposure issue allows attackers with access to a malicious or compromised repository to forward local secrets, such as API tokens, cloud credentials, and broker tokens, into the remote command environment. This occurs due to overly permissive environment variable allowlisting in the repo-local configuration, which enables the serialization of sensitive environment variables into remote command execution, thereby exposing credentials to the remote environment.

Recommendations Update to version 0.12.0 or later.
