CVE-2026-58372

SeaweedFS < 4.34 - Cross-Bucket Object Deletion via DeleteObjects Request-Body Keys

Published Jun 30, 2026 CVSS 4.0 · 7.2 High EPSS < 1% KEV · Not listed
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.
