The vulnerability lies within the Islo provider\u0026rsquo;s workspace path resolution logic. By supplying specially crafted \u003ccode\u003e.crabbox.yaml\u003c/code\u003e or \u003ccode\u003ecrabbox.yaml\u003c/code\u003e files containing directory traversal sequences (e.g., \u003ccode\u003e../\u003c/code\u003e), attackers can manipulate the application to resolve paths outside the intended \u003ccode\u003e/workspace\u003c/code\u003e directory. When the \u003ccode\u003esync.delete\u003c/code\u003e option is enabled, this vulnerability allows for arbitrary file deletion and overwrite because the application uses \u003ccode\u003erm -rf\u003c/code\u003e and \u003ccode\u003emkdir -p\u003c/code\u003e on the attacker-controlled, resolved path without proper input sanitization.
