ApostropheCMS: Path traversal in uploadfs

影響: npm:uploadfs < 1.28.0 → 1.28.0

The uploadfs library's local storage backend does not validate or sanitize user-supplied paths. The prefixPath() helper only strips double slashes (//) and the backend performs direct string concatenation (uploadsPath + path). An attacker can inject ../ sequences to escape the intended uploads directory, resulting in arbitrary file read, write, and delete on the host filesystem. --- Details Root Cause packages/uploadfs/uploadfs.js:652-655 https://github.com/apostrophecms/apostrophe/blob…
