CVE-2026-58372 - SeaweedFS < 4.34 - Cross-Bucket Object Deletion via DeleteObjects Request-Body Keys
CVE ID :CVE-2026-58372
Published : June 30, 2026, 3:57 p.m. | 2 hours, 45 minutes ago
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.
Severity: 8.1 | HIGH
