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 SAML SSO Standard WordPress plugin version 16.0.0 before 16.0.8, SAML SSO Premium WordPress plugin version 12.0.0 before 12.1.0 and SAML SSO Premium Multisite WordPress plugin version 20.0.0 before 20.0.7 does not validate that the redirect parameter to its SSO login endpoint points to an internal site URL, making it vulnerable to an Open Redirect issue when the user is already logged in.

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 SAML SSO WordPress plugins (Standard, Premium, and Premium Multisite) contain an open redirect vulnerability in their SSO login endpoint. The redirect parameter is not validated to ensure it points to an internal site URL, allowing authenticated users to be redirected to external malicious sites when they are already logged in.

MitigationUpdate the plugin to version 16.0.8 (Standard), 12.1.0 (Premium), or 20.0.7 (Premium Multisite) to obtain the fix that validates the redirect parameter points to an internal URL.

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 installed Miniorange SAML SSO plugin variant
    Check the WordPress plugin directory for either 'miniorange-saml-20-sso', 'miniorange-saml-sso', or 'miniorange-saml-sp-sso' directories. Also check plugin name in wp-admin > Plugins.
    Affected if Any of these three plugin directories exist in the WordPress plugins folder.
  2. Retrieve installed plugin version number
    In WordPress admin, go to Plugins > Installed Plugins and find the version number listed under the plugin name. Alternatively, check the 'readme.txt' or main plugin PHP file header for the 'Version' field.
    Affected if A version number is found in the plugin files.
  3. Compare version against affected ranges
    Match the installed version to these ranges: Standard (Premium): >=12.0.0 and <12.1.0; Standard: >=16.0.0 and <16.0.8; Premium Multisite: >=20.0.0 and <20.0.7.
    Affected if The installed version falls into any of these three ranges.
  4. Verify plugin is active
    Check if the plugin status in WordPress admin Plugins page shows 'Active'. The vulnerability requires the SSO login endpoint to be accessible, which only works when the plugin is active.
    Affected if The plugin is currently activated on the WordPress site.

A user is affected if they have any Miniorange SAML SSO plugin variant (Standard, Premium, or Premium Multisite) active with a version matching the affected ranges: 12.0.x, 16.0.x through 16.0.7, or 20.0.x through 20.0.6.
