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
Server-Side Request Forgery (SSRF) vulnerability in Apache ServiceComb Service-Center. Attackers can obtain sensitive server information through specially crafted requests.This issue affects Apache ServiceComb before 2.1.0(include). Users are recommended to upgrade to version 2.2.0, which fixes the issue.

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 · high confidence

This is a Server-Side Request Forgery (SSRF) vulnerability in Apache ServiceComb Service-Center. Attackers can craft malicious requests that force the server to make unintended connections to internal resources, potentially exposing sensitive information such as cloud metadata, internal services, or configuration data.

MitigationUpgrade Apache ServiceComb Service-Center to version 2.2.0 or later. If immediate upgrading is not feasible, implement network segmentation and firewall rules to restrict outbound connections from the Service-Center to internal resources.

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 Service-Center version
    Check the installed version of Apache ServiceComb Service-Center by querying the service version endpoint, checking the binary/package version, or reviewing the build metadata. Common methods: check /opt/servicecomb/version or equivalent installation directory, or query the API /v4/ and inspect the version field in the response.
    Affected if The installed version is any release prior to 2.2.0 (for example, 2.1.x, 2.0.x, 1.x series)
  2. Confirm service is network accessible
    Verify whether the Service-Center API port (default 30100 for HTTP, 30101 for gRPC) is exposed to network interfaces accessible from untrusted sources. Use netstat, ss, or firewall rules to enumerate listening ports and their binding addresses.
    Affected if The service is listening on 0.0.0.0 or an IP accessible from untrusted networks rather than only on localhost/127.0.0.1 or trusted internal interfaces
  3. Review API request handling
    Inspect the Service-Center API endpoints, particularly those that accept URL or endpoint parameters in requests (such as registry, discovery, or dependency-related endpoints). Look for requests that might allow user-controlled URL input that could trigger server-side requests.
    Affected if The service processes API requests from untrusted sources that could include URL parameters capable of triggering outbound connections to arbitrary internal resources

You are affected if your Service-Center version is below 2.2.0 AND the service API is accessible from untrusted networks, allowing attackers to inject malicious URLs that the server will fetch.

dbcve · scoped
Upgrade available Upgrade to 2.2.0 or later
Fixed in 2.2.0
Interim mitigation

Upgrade Apache ServiceComb Service-Center to version 2.2.0 or later. If immediate upgrading is not feasible, implement network segmentation and firewall rules to restrict outbound connections from the Service-Center to internal resources.

Recommended fix High confidence

2.2.0

  1. 1. Download Apache ServiceComb Service-Center version 2.2.0 from the official Apache release repositories (downloads.apache.org)
  2. 2. Back up your current Service-Center configuration and any persistent data
  3. 3. Stop the running Service-Center instance
  4. 4. Install or upgrade to version 2.2.0 using your deployment method (binary or container)
  5. 5. Restore your backed-up configuration
  6. 6. Start the Service-Center instance and verify it operates normally
Caveat Review the 2.2.0 release notes for any configuration or API changes compared to your current version
