CVE-2026-58372 Details
Description
SeaweedFS before 4.34 contains a path traversal vulnerability in the S3 gateway DeleteMultipleObjectsHandler that allows authenticated S3 principals with write access to a single bucket to delete arbitrary objects in other tenants' buckets by supplying object keys containing ../ sequences in the DeleteObjects XML request body. Attackers can bypass authorization controls through a confused deputy condition, as the validateRequestPath middleware only inspects URL-captured path variables and never examines request-body keys, allowing the filer path to collapse directory traversal sequences and resolve deletions outside the authorized bucket.
A path traversal vulnerability has been identified in SeaweedFS versions prior to 4.34, specifically within the S3 gateway's DeleteMultipleObjectsHandler. This vulnerability allows authenticated S3 principals with write access to a single bucket to delete arbitrary objects in other tenants' buckets. The issue arises from the handling of object keys in the DeleteObjects XML request body, which can be manipulated to include ../ sequences, bypassing authorization controls and causing unauthorized deletions.
Users can upgrade to SeaweedFS version 4.30 or later, where this vulnerability has been fixed. Instructions for downloading the latest version can be found in the SeaweedFS release notes.
