CVE ID :CVE-2026-57856<\/p>\n
Published : July 13, 2026, 11:16 p.m. | 13\u00a0minutes ago<\/p>\n
Description :Cockpit CMS contains a path traversal vulnerability in the Bucket file storage API (\/system\/buckets\/api). The api() method in modules\/System\/Controller\/Buckets.php sanitizes the bucket name with preg_replace(‘\/[^a-zA-Z0-9-_\\.]\/’,”, $bucket), which permits ‘..’ and ‘..\/’ sequences. The sanitized value is interpolated into a Flysystem path as uploads:\/\/buckets\/{bucket}. Flysystem’s WhitespacePathNormalizer resolves ‘buckets\/..’ to the empty string (the uploads storage root) without raising PathTraversalDetected because the ‘..’ has a preceding component to consume. An authenticated low-privileged user can send a crafted request with a ‘..\/’ bucket name to list, upload, and delete files across all buckets, including those belonging to other users or roles<\/p>\n
Severity: 8.8 | HIGH<\/p>\n
