MEDIUMRailsAdmin Cross-site Scripting vulnerability in the list view
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for rails_admin. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
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.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-8qgm-g2vv-vwvc is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-8qgm-g2vv-vwvc. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-8qgm-g2vv-vwvc in your dependencies?
O3 detects GHSA-8qgm-g2vv-vwvc across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
