Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
New Cloud MyOffice SDK Collaborative Editing Server 2.2.2 through 2.8 allows SSRF via manipulation of requests from external document storage via the MS-WOPI protocol.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

New Cloud MyOffice SDK Collaborative Editing Server versions 2.2.2 through 2.8 contains a Server-Side Request Forgery (SSRF) vulnerability in its MS-WOPI protocol integration with external document storage. Attackers can manipulate outgoing requests from the server to internal or external resources, potentially accessing sensitive internal services, cloud metadata endpoints, or performing reconnaissance.

MitigationRestrict outgoing network connections from the Collaborative Editing Server using network segmentation and allowlists. Validate and sanitize all URLs and hostnames in WOPI protocol requests before making outgoing connections, and implement strict schema and destination constraints.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed MyOffice SDK version
    Locate the Cloud MyOffice SDK installation and check its version number (commonly visible in the application header, about page, or installation directory metadata).
    Affected if The installed version falls within >= 2.2.2 and <= 2.8.0.
  2. Confirm WOPI protocol integration is active
    Examine the MyOffice server configuration files or admin interface for WOPI protocol settings. Look for entries indicating WOPI integration for external document storage.
    Affected if WOPI protocol integration is enabled and configured for external document storage.
  3. Inspect WOPI endpoint configuration
    Review the WOPI handler configuration files or admin panel for configured storage endpoint URLs. Check whether URL allowlisting or validation rules are defined.
    Affected if No URL allowlisting is enforced, or arbitrary URLs can be specified as WOPI storage endpoints.
  4. Review network access controls
    Examine server firewall rules, network segmentation settings, and outbound access policies controlling where the server can initiate HTTP/HTTPS connections.
    Affected if The server has unrestricted outbound network access, allowing connections to internal infrastructure or arbitrary external addresses.

You are affected if your installed MyOffice SDK version is between 2.2.2 and 2.8.0 inclusive, WOPI protocol integration is enabled, and there are no strict URL validation or network restrictions in place.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Interim mitigation

Restrict outgoing network connections from the Collaborative Editing Server using network segmentation and allowlists. Validate and sanitize all URLs and hostnames in WOPI protocol requests before making outgoing connections, and implement strict schema and destination constraints.
