CVE-2023-23787
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 · uneditedCross-Site Request Forgery (CSRF) vulnerability in Premmerce Premmerce Redirect Manager plugin <= 1.0.9 versions.
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 confidenceCross-Site Request Forgery (CSRF) vulnerability in Premmerce Redirect Manager plugin for WordPress versions 1.0.9 and below. The lack of anti-CSRF tokens on state-changing operations (likely redirect creation/modification/deletion) allows attackers to trick authenticated administrators into performing unintended actions.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Premmerce Redirect Manager is installedNavigate to WordPress Admin > Plugins or check the filesystem at wp-content/plugins/ for a directory named 'premmerce-redirect-manager' or similar premmerce prefix.Affected if The plugin directory exists in the WordPress installation
-
Identify the installed plugin versionOpen the main plugin PHP file (usually premmerce-redirect-manager.php) and locate the Version header in the plugin comment block, or check the version in the WordPress Plugins admin page.Affected if The reported version is 1.0.9 or lower (e.g., 1.0.8, 1.0.7, etc.)
-
Locate state-changing functionality in plugin codeSearch the plugin directory for files handling redirect operations - look for terms like 'create_redirect', 'update_redirect', 'delete_redirect', 'add_redirect', or form handlers in admin menu pages.Affected if Files exist that process redirect creation, modification, or deletion requests
-
Inspect redirect handlers for missing nonce verificationOpen the identified redirect handler files and search for absence of WordPress nonce functions: wp_nonce_field, check_admin_referer, wp_verify_nonce, or verify_nonce. Check form submission handlers and AJAX action callbacks.Affected if State-changing functions (redirect add/edit/delete) lack nonce verification calls like check_admin_referer() or wp_verify_nonce()
-
Verify admin access to redirect management interfaceLog into WordPress admin as an administrator and navigate to the Premmerce Redirect Manager menu (typically under Tools or a dedicated menu item) to confirm the redirect management UI is accessible.Affected if The redirect management interface is accessible to authenticated administrators
Your environment is affected if the Premmerce Redirect Manager plugin is installed with version 1.0.9 or lower and the code handling redirect operations lacks WordPress nonce verification on form submissions or AJAX requests.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedImplement WordPress nonces (nonce tokens) on all form submissions and AJAX requests that modify redirects, and verify the nonce validity server-side before executing any state-changing operation. Update to a patched version if available.
Version 1.1.0 or later (the first version after 1.0.9)
- 1. Log in to the WordPress admin dashboard
- 2. Navigate to Plugins > Installed Plugins
- 3. Locate the Premmerce Redirect Manager plugin
- 4. Check if an update is available and update to the latest version
- 5. If no update is available through WordPress, download the latest version from the WordPress plugin repository or contact Premmerce support
- 6. Verify the update was successful and test the redirect functionality
