CVE-2026-8634

Full vulnerability record from the local CVENow database.

Description

Crabbox prior to v0.12.0 contains an environment variable exposure vulnerability that 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. Attackers can exploit overly permissive environment variable allowlisting in repo-local Crabbox configuration to serialize sensitive environment variables into remote command execution, exposing credentials to the remote environment.

Los atacantes pueden explotar una lista blanca de variables de entorno excesivamente permisiva en la configuración de Crabbox local del repositorio para serializar variables de entorno sensibles en la ejecución remota de comandos, exponiendo credenciales al entorno remoto."
