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 Local Syndication plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.5a via the `url` parameter in the `[syndicate_local]` shortcode. This is due to the use of `wp_remote_get()` instead of `wp_safe_remote_get()` which lacks protections against requests to internal/private IP addresses and localhost. This makes it possible for authenticated attackers, with Contributor-level access and above, to make web requests to arbitrary locations originating from the web application, which can be used to query and modify information from internal services, scan internal networks, and access resources that should not be accessible from external networks.

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 Local Syndication WordPress plugin uses `wp_remote_get()` instead of the safer `wp_safe_remote_get()` in its `[syndicate_local]` shortcode. This allows authenticated attackers with Contributor-level access or higher to supply arbitrary URLs via the `url` parameter, enabling SSRF attacks to internal services, private IP addresses, and localhost resources.

MitigationReplace `wp_remote_get()` with `wp_safe_remote_get()` in the shortcode handler to prevent requests to internal/private IP addresses and localhost, or implement URL allowlist validation for permitted external destinations.

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 Local Syndication plugin is installed
    In WordPress admin, go to Plugins > Installed Plugins and search for 'Local Syndication' or check wp-content/plugins/ directory for the syndication-local folder
    Affected if The plugin is installed and active
  2. Confirm plugin version
    Check the plugin header in syndication-local/syndication-local.php for the Version: field, or view in Plugins list in WordPress admin
    Affected if Version is unknown or unpatched (no fixed version specified in CVE)
  3. Detect vulnerable function call in shortcode handler
    Search plugin files for 'wp_remote_get' in the shortcode handler: grep -r 'wp_remote_get' wp-content/plugins/syndication-local/ and examine the context around the [syndicate_local] shortcode function
    Affected if Code uses wp_remote_get() instead of wp_safe_remote_get() in the shortcode handler
  4. Identify Contributor-level or higher users
    In WordPress admin, go to Users > All Users and filter by role; check for Contributor, Author, Editor, or Administrator roles
    Affected if At least one user with Contributor-level access or higher exists who could supply the url parameter

If the Local Syndication plugin is active, uses wp_remote_get() in its [syndicate_local] shortcode, and has any Contributor+ users, the environment is vulnerable to SSRF via the url parameter.
