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
A vulnerability, which was classified as critical, was found in quequnlong shiyi-blog up to 1.2.1. Affected is an unknown function of the file /api/sys/user/verifyPassword/ of the component Administrator Backend. The manipulation leads to improper authentication. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

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

Critical authentication bypass vulnerability in shiyi-blog admin backend. The /api/sys/user/verifyPassword/ endpoint allows unauthenticated remote attackers to verify or potentially reset administrator passwords, granting full admin access to the application.

MitigationImmediately restrict the verifyPassword endpoint to require valid administrator authentication. Implement proper session validation and authorization checks on all admin API endpoints. Consider disabling the application remotely until patched.

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 shiyi-blog installed version
    Locate the application version file or check the admin interface for the version number. Common locations include: pom.xml, package.json, version metadata in the admin dashboard, or the application startup logs.
    Affected if The installed version is 1.2.1 or lower.
  2. Verify the vulnerable endpoint exists
    Check if the application exposes the /api/sys/user/verifyPassword/ endpoint. This can be done by reviewing the application's API routing configuration or attempting to access the endpoint path.
    Affected if The /api/sys/user/verifyPassword/ endpoint is present and routable in the application.
  3. Test endpoint authentication requirement
    Send a request to /api/sys/user/verifyPassword/ without any authentication headers, cookies, or session tokens. Use a tool like curl: curl -X POST http://TARGET/api/sys/user/verifyPassword/ -H "Content-Type: application/json" -d '{"password":"test"}'
    Affected if The endpoint responds without requiring authentication (returns 200 OK instead of 401 Unauthorized or 403 Forbidden).

You are affected if shiyi-blog version is 1.2.1 or lower AND the /api/sys/user/verifyPassword/ endpoint is accessible without authentication.
