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

A persistent (stored) cross-site scripting vulnerability exists in the Blog Post component of Elefant CMS version 1.3.12-RC. Attackers can inject malicious JavaScript code into blog post content, which is then stored and executed when other users view the affected posts.

MitigationUpgrade Elefant CMS to version 1.3.13 which contains the fix for this XSS vulnerability. As a defense-in-depth measure, implement output encoding and content security policy headers.

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 Elefant CMS version
    Locate the version file or composer.json in the Elefant CMS installation directory and read the version number
    Affected if The installed version is exactly 1.3.12 or 1.3.12-RC
  2. Verify Blog Post component is active
    Check if the Blog module is installed and enabled by inspecting the /apps directory for the blog component or checking the CMS modules list
    Affected if The Blog Post component is installed and enabled in the CMS
  3. Inspect stored blog post content
    Access the blog post database or admin interface and review recent entries for suspicious script tags, iframe embeddings, or event handlers in the post content fields
    Affected if Any blog posts contain unescaped HTML or JavaScript tags (such as <script>, <img onerror>, or javascript: URIs)
  4. Check CMS user sessions for compromise
    Review server access logs and CMS audit logs for XSS payload patterns and suspicious session activity originating from blog post viewing
    Affected if Logs show repeated attempts to inject XSS payloads or successful execution of injected scripts in blog posts

You are affected if running Elefant CMS version 1.3.12 with the Blog Post component enabled and any stored blog posts exist, since the stored XSS can execute when users view those posts.
