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

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

CSRF vulnerability in Z-BlogPHP 1.5.1 plugin_edit.php allows attackers to trick authenticated administrators into submitting malicious requests, enabling arbitrary PHP code execution on the server.

MitigationImplement anti-CSRF tokens (synchronizer token pattern) in all state-changing forms including plugin_edit.php, validate the Origin/Referer headers, and apply SameSite attribute to session cookies.

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. Verify Z-BlogPHP installation version
    Locate the version file or admin dashboard about page for Z-BlogPHP and confirm the installed version number
    Affected if Version is exactly 1.5.1
  2. Confirm plugin_edit.php exists
    Check for the presence of the file plugin_edit.php in the Z-BlogPHP admin or application directory structure
    Affected if The file plugin_edit.php exists in the installation
  3. Inspect plugin_edit.php for CSRF token implementation
    Open plugin_edit.php in a text editor and search for anti-CSRF token validation logic, such as checks for a token parameter, session validation, or call to a token verification function
    Affected if No anti-CSRF token mechanism is found in the code
  4. Check form submission in plugin_edit.php for token field
    Examine HTML forms within plugin_edit.php to determine if a hidden token field or synchronizer token pattern is included with each state-changing form submission
    Affected if Forms lack a hidden CSRF token field

A user is affected if running Z-BlogPHP version 1.5.1 and the plugin_edit.php file lacks anti-CSRF token protection on its forms.
