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 confidence

Cross-Site Request Forgery (CSRF) vulnerability in the RIS Version Switcher WordPress plugin allows remote attackers to trick authenticated administrators into performing unintended actions such as downgrading or upgrading WordPress versions via crafted requests. The vulnerability affects all versions up to and including 1.0 due to missing or insufficient anti-CSRF token validation on state-changing operations.

MitigationImplement WordPress nonces (anti-CSRF tokens) on all form submissions and AJAX actions within the plugin that modify WordPress version settings, and verify the nonce validity server-side before executing any state-changing operations.

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 RIS Version Switcher plugin is installed
    Check the WordPress plugins directory for the RIS Version Switcher plugin folder, typically at wp-content/plugins/ris-version-switcher/ or similar naming convention, and list its files.
    Affected if The plugin folder exists in the WordPress plugins directory
  2. Identify installed plugin version
    Open the main plugin PHP file or readme.txt within the plugin directory and locate the version declaration (usually in a comment block at the top or in the 'Version' header).
    Affected if The version is 1.0 or any version up to and including 1.0
  3. Inspect plugin for state-changing operations
    Examine the plugin PHP files for form handling code, particularly any functions that modify WordPress version settings or perform upgrade/downgrade actions. Look for admin_init, admin_post, or AJAX handlers.
    Affected if The plugin contains code that modifies WordPress version settings without explicit mention of nonce verification
  4. Check for anti-CSRF nonce validation in form handlers
    Search the plugin PHP files forwp_nonce_field, wp_verify_nonce, check_admin_referer, or similar nonce verification functions within the same files or functions that handle state-changing operations.
    Affected if No nonce verification functions are found in the code handling WordPress version changes, or nonce checks are absent in the relevant form/AJAX handlers
  5. Confirm admin access to vulnerable functionality
    Log into WordPress as an administrator and navigate to any settings pages provided by the RIS Version Switcher plugin to verify the plugin exposes version switching controls.
    Affected if The plugin admin interface is accessible and exposes controls to change WordPress versions without visible CSRF protection indicators

If the RIS Version Switcher plugin is installed at version 1.0 or below and its version-switching functionality lacks nonce validation on state-changing operations, the environment is affected by CVE-2025-57902.
