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 security flaw has been discovered in moxi159753 Mogu Blog v2 up to 5.2. Impacted is the function LocalFileServiceImpl.uploadPictureByUrl of the file /file/uploadPicsByUrl. The manipulation results in server-side request forgery. The attack can be launched remotely. The exploit has been released to the public and may be exploited. 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

Server-Side Request Forgery (SSRF) vulnerability in the /file/uploadPicsByUrl endpoint of Mogu Blog v2 allows remote attackers to make the server fetch arbitrary URLs through the LocalFileServiceImpl.uploadPictureByUrl function, potentially exposing internal services and data.

MitigationDisable or restrict the /file/uploadPicsByUrl endpoint, implement strict URL allow-listing with validation, and apply network segmentation to prevent internal service exposure.

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. Confirm Mogu Blog installation
    Identify if the Mogu Blog application is deployed on your server by checking web application files, services, or HTTP headers for 'mogublog' or 'Mogu' identifiers.
    Affected if Mogu Blog v2 is installed on the server
  2. Check installed version
    Locate and read the version file or build configuration (such as pom.xml, application.yml, or a version manifest) to determine the exact Mogu Blog version.
    Affected if The installed version is 5.2 or any lower version
  3. Verify endpoint accessibility
    Send an HTTP GET or POST request to the /file/uploadPicsByUrl endpoint to confirm it is exposed and reachable.
    Affected if The endpoint responds and accepts requests (indicating it is not disabled or restricted)
  4. Confirm vulnerable module is active
    Inspect the deployed application code or configuration to verify that LocalFileServiceImpl with the uploadPictureByUrl function is loaded and operational.
    Affected if LocalFileServiceImpl.uploadPictureByUrl is present and enabled in the application

You are affected if Mogu Blog v2 version 5.2 or lower is running and the /file/uploadPicsByUrl endpoint is accessible with the LocalFileServiceImpl module enabled.
