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
The Blog2Social: Social Media Auto Post & Scheduler plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'deleteUserCcDraftPost' function in all versions up to, and including, 8.7.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change the status of arbitrary posts to trash.

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

The Blog2Social WordPress plugin versions up to 8.7.0 lacks a capability check on the 'deleteUserCcDraftPost' function, allowing any authenticated user with Subscriber-level privileges to modify post statuses and trash arbitrary posts they do not own. This is a Broken Access Control (IDOR) vulnerability.

MitigationUpdate the Blog2Social plugin to version 8.7.1 or later which includes proper capability validation. Until patched, consider restricting user registration or using a WAF to mitigate exploitation.

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 if Blog2Social plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and look for Blog2Social, or check the /wp-content/plugins/ directory for the blog2social folder
    Affected if The plugin is installed and the version is 8.7.0 or lower
  2. Determine the installed version of Blog2Social
    In WordPress admin > Plugins > Installed Plugins, find Blog2Social and note the version number displayed below the plugin name
    Affected if The version listed is 8.7.0 or any version below 8.7.1 (e.g., 8.6.9, 8.5.0, etc.)
  3. Verify the Subscriber role exists on the site
    Go to WordPress admin > Users > Users and look for the 'Subscriber' role in any user row, or use a user role editor plugin to list all roles
    Affected if The Subscriber role is present in the WordPress installation
  4. Check if any users have Subscriber-level access
    In WordPress admin > Users > Users, filter or search for users with the Subscriber role, or check the wp_usermeta table for meta_key='wp_capabilities' containing 'subscriber'
    Affected if There is at least one user account with Subscriber role (even a newly registered account)
  5. Confirm the vulnerable function exists in the plugin code
    Access the WordPress files via FTP or file manager, navigate to /wp-content/plugins/blog2social/includes/, and search for the function 'deleteUserCcDraftPost' in the PHP files
    Affected if The function deleteUserCcDraftPost is found in the plugin code without a capability check (the function exists in versions up to 8.7.0)

You are affected if Blog2Social plugin versions 8.7.0 or below are installed, the Subscriber role exists, and there is at least one Subscriber-level user account on the site.
