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
Mediawiki before 1.28.1 / 1.27.2 / 1.23.16 contains a flaw where Special:Search allows redirects to any interwiki link.

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

MediaWiki before versions 1.28.1, 1.27.2, and 1.23.16 contains an open redirect vulnerability in Special:Search that allows redirects to arbitrary interwiki links. An attacker could craft malicious URLs that appear to originate from the trusted wiki domain but redirect users to external sites, facilitating phishing or credential theft attacks.

MitigationUpgrade MediaWiki to version 1.28.1, 1.27.2, or 1.23.16 or later to patch the vulnerable Special:Search redirect functionality.

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. Determine installed MediaWiki version
    Check the includes/Defines.php file or the Special:Version page on your wiki for the exact version number
    Affected if The version falls within 1.23.0-1.23.16, 1.27.0-1.27.1, or 1.28.0-1.28.0
  2. Verify Special:Search is accessible
    Confirm the Special:Search special page exists and is accessible on your MediaWiki installation
    Affected if Special:Search is available (this is the default state for any MediaWiki installation)
  3. Check if full-text search is enabled
    Look for the $wgSearchType configuration setting in your LocalSettings.php file - if set to a valid search engine or left default, the search functionality including redirects is active
    Affected if Search functionality is enabled (the default configuration)

Your wiki is affected if it runs any MediaWiki version from 1.23.0 through 1.23.16, 1.27.0 through 1.27.1, or 1.28.0 through 1.28.0 with the default search functionality enabled.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.
