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

A cross-site scripting (XSS) vulnerability exists in Rebuild CMS versions up to 3.2.3 in the /feeds/post/publish endpoint. An attacker can inject malicious scripts through unspecified vectors in this functionality, which executes in the context of other users' browsers.

MitigationUpgrade Rebuild CMS to a version beyond 3.2.3 that includes the security patch, or implement input validation and output encoding on the /feeds/post/publish endpoint to neutralize malicious script payloads.

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 Rebuild CMS installation and version
    Locate the CMS installation directory or check the administrative dashboard for the installed version number. Common paths include the web root where Rebuild CMS is deployed. The version is typically displayed in the admin interface footer or in a version file within the installation.
    Affected if The installed version is 3.2.3 or any version lower than 3.2.3
  2. Confirm version is within affected range
    Compare your identified version against the affected range: Ruifang Tech Rebuild CMS version 3.2.3 and below. If your version is exactly 3.2.3 or any earlier release, it falls within the vulnerable range.
    Affected if The installed version is less than or equal to 3.2.3
  3. Verify the /feeds/post/publish endpoint exists
    Access your Rebuild CMS web application and navigate to or request the /feeds/post/publish endpoint. This is typically found in the feeds or publishing section of the CMS where posts can be submitted. Check if the endpoint responds to requests.
    Affected if The /feeds/post/publish endpoint is accessible and responds to requests in your CMS installation
  4. Check if endpoint accepts user input without sanitization
    Submit a test payload through the /feeds/post/publish endpoint, such as a simple HTML tag or script alert, and observe if the input is reflected back in the response without encoding or sanitization. This requires functional testing of the endpoint.
    Affected if User-supplied input in the /feeds/post/publish endpoint is reflected in responses without proper encoding or input validation

Your environment is affected if Rebuild CMS version 3.2.3 or lower is installed and the /feeds/post/publish endpoint is accessible and processes input without sanitization.
