Description
Crabbox before 0.9.0 contains a path traversal vulnerability in the Islo provider's workspace path resolution that allows attackers to supply absolute or relative paths that resolve outside the intended /workspace directory. Attackers can craft a malicious .crabbox.yaml or crabbox.yaml file with traversal sequences to cause arbitrary file deletion and overwrite when sync.delete is enabled, as the workspace preparation logic executes rm -rf and mkdir -p operations on the resolved path without proper validation.
