CVE-2026-54917: Technical Details & Impact

What is CVE-2026-54917 and which systems are affected?

CVE-2026-54917 is a high-severity path traversal vulnerability (CWE-22) in SeaweedFS, a distributed storage system supporting S3-compatible object storage and Apache Iceberg table management. The flaw allows unauthenticated remote attackers to read from or write to arbitrary storage buckets without authorization. All SeaweedFS versions prior to v4.30 are affected. Note: Only SeaweedFS deployments with network-reachable S3 API or Iceberg REST catalog gateways are vulnerable. Source: NIST CVE-2026-54917, June 26, 2026. Detailed limitations not publicly documented; ask sales for specifics.

How does the CVE-2026-54917 vulnerability work?

The vulnerability arises because the S3 API gateway and Iceberg REST catalog gateway in SeaweedFS initialize their HTTP routers with SkipClean(true), disabling URL path normalization. Attackers can send crafted HTTP requests with .. segments (e.g., GET /bucket-A/../evil-bucket/key), which bypass bucket isolation and allow unauthorized cross-bucket access. This enables both data exfiltration and tampering. Note: The vulnerability is fixed in SeaweedFS v4.30. Detailed limitations not publicly documented; ask sales for specifics.

What is the recommended mitigation for CVE-2026-54917?

Upgrade SeaweedFS to version 4.30 or later. The fix introduces validation middleware that rejects URL path variables containing traversal segments (..), null bytes, or embedded slashes. If immediate patching is not possible, restrict network access to the S3 API gateway (default port 8333) and Iceberg REST catalog gateway using firewall rules to limit exposure to trusted networks. Do not expose these interfaces directly to the internet. Note: These mitigations reduce risk but do not fully remediate the vulnerability until patched. Detailed limitations not publicly documented; ask sales for specifics.

CVE-2026-54917 – Cross-Bucket Authorization Bypass – SeaweedFS prior to v4.30

Be the first to know when new zero-days emerge:

Summary

CVE-2026-54917 is a high-severity path traversal vulnerability (CWE-22) affecting SeaweedFS, a widely-deployed distributed storage system offering S3-compatible object storage and Apache Iceberg table management. The flaw resides in the S3 API gateway and the Iceberg REST catalog gateway, and allows any unauthenticated remote attacker to read from or write to arbitrary storage buckets they are not authorized to access. The vulnerability is fixed in SeaweedFS v4.30.

Technical details

  • Root cause: Both the S3 API gateway and the Iceberg REST catalog gateway initialize their HTTP routers with mux.NewRouter().SkipClean(true), which disables URL path cleaning. As a result, .. segments embedded in a request URL survive the routing layer without being normalized.
  • Trigger condition: An attacker sends a crafted HTTP request such as GET /bucket-A/../evil-bucket/key. The router matches bucket-A as the bucket and ../evil-bucket/key as the object key. The object key is then joined into a filer path using util.JoinPath (S3 gateway) or path.Join (Iceberg gateway), which collapses the .. server-side, so the actual storage operation resolves to evil-bucket.
  • Attack vector: Network-reachable, no authentication required, no user interaction required. URL-encoded variants (%2e%2e) produce identical results. The vulnerability affects multiple captured path variables including {bucket}, {prefix}, {namespace}, and {table}.
  • Impact: An unauthenticated attacker can perform unauthorized cross-bucket reads (data exfiltration) and cross-bucket writes (data tampering or injection). In deployments with authentication enabled, the bypass breaks tenant isolation and allows access to buckets beyond any granted permissions. The CVSS 4.0 vector assigns Subsequent System Confidentiality: HIGH (SC:H) and Subsequent System Integrity: HIGH (SI:H).

Affected software

  • SeaweedFS — all versions prior to 4.30

Severity

  • CVSS 4.0 Base Score: 7.8 (HIGH)
  • Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:N
  • CWE: CWE-22 – Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’)

Note: NIST has not yet published a CVSS v3.1 score for this CVE as of the publication date. The CVSS 4.0 score above is sourced directly from the CVE record.

Mitigation and recommended actions

  • Immediate: Upgrade SeaweedFS to v4.30 or later. The fix introduces a validation middleware that rejects captured URL path variables containing traversal segments (..), null bytes, or embedded slashes before any handler executes.
  • If patching is not immediately feasible: Restrict network access to the SeaweedFS S3 API gateway (default port 8333) and the Iceberg REST catalog gateway using firewall rules or network-level controls to limit exposure to trusted networks only. Do not expose these interfaces directly to the internet.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
