How severe is GHSA-8qgm-g2vv-vwvc?

GHSA-8qgm-g2vv-vwvc has a CVSS score of 6.8/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-8qgm-g2vv-vwvc?

GHSA-8qgm-g2vv-vwvc affects the following packages: rails_admin (RubyGems). Ecosystems affected: RubyGems.

How do I fix GHSA-8qgm-g2vv-vwvc?

Update rails_admin to 3.1.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8qgm-g2vv-vwvc is resolved across your whole dependency graph.

How do I detect GHSA-8qgm-g2vv-vwvc in my RubyGems dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for rails_admin, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-8qgm-g2vv-vwvc if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is GHSA-8qgm-g2vv-vwvc actively exploited in the wild?

No public exploit code has been indexed for GHSA-8qgm-g2vv-vwvc yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-8qgm-g2vv-vwvc?

GHSA-8qgm-g2vv-vwvc has an EPSS (Exploit Prediction Scoring System) score of 0.6%, placing it in the 48th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-8qgm-g2vv-vwvc?

Description

Impact

RailsAdmin list view has the XSS vulnerability, caused by improperly-escaped HTML title attribute. The issue was originally reported in https://github.com/railsadminteam/rails_admin/issues/3686.

Patches

Upgrade to 3.1.4. The vulnerability itself was patched in 3.1.3 but it has a functionality issue. Initially the vulnerability was thought to exist in versions before 3.0, but it didn't. 2.x users can stay on 2.2.1.

Workarounds

Copy the index view (located under the path app/views/rails_admin/main/index.html.erb) from the RailsAdmin version you use, and place it into your application by using the same path.
Open the view file by an editor, and change the way to populate the td tag:

               <% properties.map{ |property| property.bind(:object, object) }.each do |property| %>
                 <% value = property.pretty_value %>
-                <td class="<%= [property.sticky? && 'sticky', property.css_class, property.type_css_class].select(&:present?).join(' ') %>" title="<%= value %>">
+                <%= content_tag(:td, class: [property.sticky? && 'sticky', property.css_class, property.type_css_class].select(&:present?), title: strip_tags(value.to_s)) do %>
                   <%= value %>
-                </td>
+                <% end %>
               <% end %>

Note: The view file created by this needs to be removed after upgrading RailsAdmin afterwards, unless this old view continue to be used. Only do this if you can't upgrade RailsAdmin now for a reason.
