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
Redmine before 4.2.9 and 5.0.x before 5.0.4 allows persistent XSS in its Textile formatter due to improper sanitization in Redcloth3 Textile-formatted fields. Depending on the configuration, this may require login as a registered user.

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

Redmine versions before 4.2.9 and 5.0.4 contain a persistent XSS vulnerability in the Textile formatter (Redcloth3) where Textile-formatted fields are not properly sanitized, allowing attackers to inject malicious scripts that execute in other users' browsers.

MitigationUpgrade Redmine to version 4.2.9, 5.0.4, or later. Until upgraded, restrict or disable Textile formatting in user-editable fields or implement additional input validation.

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 Redmine version
    Access the Redmine administration panel: navigate to Administration > Information, or inspect the config/version.rb file in the Redmine installation directory, or check the version in your Gemfile.lock (look for the 'redmine' or 'Redmine' gem entry)
    Affected if The version is below 4.2.9, or is 5.0.0 through 5.0.3
  2. Determine if Textile formatting is enabled
    In the Redmine administration panel, go to Administration > Settings > Text formatting (or Project > Settings > Information on older versions). Look for the available text formatters. Check whether 'Textile' or 'Redcloth' is listed as an available format.
    Affected if Textile/Redcloth is listed as an available text formatting option
  3. Identify user-editable fields using Textile
    Review which fields allow rich text formatting. Common locations include: issue descriptions, issue notes, wiki pages, news entries, and document descriptions. Check the settings for each project under Project > Settings > Information to see which text format is selected for description fields.
    Affected if Any user-editable field (such as issue descriptions, wiki pages, or comments) is configured to use Textile formatting
  4. Verify Redcloth3 gem version (optional)
    If you have command-line access, run 'gem list redcloth3' or check your Gemfile.lock for the redcloth3 gem version
    Affected if The redcloth3 gem version is older than the version bundled with patched Redmine releases

You are affected if your Redmine version is below 4.2.9 or between 5.0.0 and 5.0.3, AND Textile/Redcloth formatting is enabled for any user-editable text fields in your installation.

Interim mitigation

Upgrade Redmine to version 4.2.9, 5.0.4, or later. Until upgraded, restrict or disable Textile formatting in user-editable fields or implement additional input validation.

Recommended fix High confidence

Redmine 4.2.9+ or 5.0.4+ (recommended: latest stable 5.x release)

  1. Backup your Redmine database and all files before proceeding
  2. Identify your current Redmine version in Administration > Information
  3. If running Redmine 4.2.x: upgrade to version 4.2.9 or later
  4. If running Redmine 5.0.x: upgrade to version 5.0.4 or later
  5. Alternatively, upgrade to the latest stable Redmine release (5.1.0 or higher if available)
  6. Test the upgrade in a staging environment before deploying to production
  7. Deploy the upgraded version to production
Caveat Minor version upgrades may introduce plugin compatibility issues; test thoroughly before production deployment
