CVE-2026-58372
Description
A flaw was found in SeaweedFS. An authenticated remote attacker with write access to a single bucket could exploit a path traversal vulnerability in the S3 gateway. By crafting a DeleteObjects XML request body with specific object keys containing directory traversal sequences, the attacker could bypass authorization controls. This allows the attacker to delete arbitrary objects in other tenants' buckets, leading to unauthorized data deletion.
Statement
SeaweedFS is affected by a path traversal vulnerability in the S3 gateway's DeleteMultipleObjectsHandler, where ../ sequences in the object keys of a DeleteObjects request body allow an authenticated client to delete objects outside its authorized bucket scope. Red Hat build of Cryostat 4 bundles SeaweedFS as its storage component (cryostat-storage) and is affected. Exploitation requires a valid S3 principal with write access in a multi-tenant deployment; Cryostat's single-tenant use of the storage backend substantially limits practical exposure. Red Hat rates the impact of this flaw as Important. This is fixed in SeaweedFS 4.34.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the criteria for vulnerability selection or Red Hat Product Security recommendation. Restricting S3 write access to trusted principals reduces the risk of exploitation.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
The attacker may be able to create or overwrite critical files that are used to execute code, such as programs or libraries.
Integrity
Technical Impact: Modify Files or Directories
The attacker may be able to overwrite or create critical files, such as programs, libraries, or important data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, appending a new account at the end of a password file may allow an attacker to bypass authentication.
Confidentiality
Technical Impact: Read Files or Directories
The attacker may be able read the contents of unexpected files and expose sensitive data. If the targeted file is used for a security mechanism, then the attacker may be able to bypass that mechanism. For example, by reading a password file, the attacker could conduct brute force password guessing attacks in order to break into an account on the system.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
The attacker may be able to overwrite, delete, or corrupt unexpected critical files such as programs, libraries, or important data. This may prevent the product from working at all and in the case of protection mechanisms such as authentication, it has the potential to lock out product users.
