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 Cloud SAML SSO plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'set_organization_settings' action of the csso_handle_actions() function in all versions up to, and including, 1.0.19. The handler reads client-supplied POST parameters for organization settings and passes them directly to update_option() without any check of the user’s capabilities or a CSRF nonce. This makes it possible for unauthenticated attackers to change critical configuration (including toggling signing and encryption), potentially breaking the SSO flow and causing a denial-of-service.

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 Cloud SAML SSO plugin for WordPress has a missing capability check vulnerability in the csso_handle_actions() function. An unauthenticated attacker can send a POST request to the 'set_organization_settings' action with arbitrary organization settings (including signing/encryption toggles), which are passed directly to update_option() without any authentication, authorization, or CSRF nonce verification.

MitigationUpdate to version 1.0.20 or later which should include capability checks and CSRF nonce validation. Until then, consider disabling the plugin or restricting access via web application firewall rules to block unauthorized requests to the affected action.

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 Cloud SAML SSO plugin is installed
    Check the WordPress plugins directory (wp-content/plugins/) for a folder named 'cloud-saml-sso' or similar, or use WP CLI: 'wp plugin list --status=active --format=csv' to list active plugins
    Affected if The plugin folder exists in wp-content/plugins/ or appears in the plugin list
  2. Determine the installed plugin version
    Open the main plugin file (usually cloud-saml-sso.php or similar in the plugin folder) and look for the version header in the plugin comment block, or use WP CLI: 'wp plugin get cloud-saml-sso --format=json'
    Affected if The version number found is lower than 1.0.20 or cannot be determined (assume vulnerable)
  3. Verify the plugin is active
    Use WP CLI: 'wp plugin is-active cloud-saml-sso' or check the WordPress database wp_options table for the active_plugins option
    Affected if The plugin is currently active in WordPress
  4. Confirm the vulnerable action is reachable
    Check if the plugin file contains the function csso_handle_actions() and the 'set_organization_settings' action handler by searching the plugin code: grep -r 'set_organization_settings' /path/to/wp-content/plugins/cloud-saml-sso/
    Affected if The function and action handler exist in the installed plugin code (confirms the vulnerable code path is present)

If the Cloud SAML SSO plugin is installed, active, and the version is below 1.0.20, the environment is vulnerable to unauthenticated configuration changes via the set_organization_settings action.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update to version 1.0.20 or later which should include capability checks and CSRF nonce validation. Until then, consider disabling the plugin or restricting access via web application firewall rules to block unauthorized requests to the affected action.

Recommended fix Moderate confidence

Version 1.0.20 or later

  1. Navigate to the WordPress admin dashboard
  2. Go to Plugins > Installed Plugins
  3. Locate the 'Cloud SAML SSO' plugin
  4. Check if an update is available and update to the latest version
  5. Verify the update was successful by checking the plugin version
