GHSA-pxr8-w3jq-rcwj
MEDIUMGHSA-pxr8-w3jq-rcwj is a medium-severity (CVSS 6.1) Cross-site Scripting (XSS) vulnerability in rails_admin. 3 public exploit references exist, so weaponization risk is real. O3 Security confirms whether GHSA-pxr8-w3jq-rcwj is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
An exploitable cross site scripting (XSS) vulnerability exists in the add filter functionality of the rails_admin rails gem version 1.2.0. A specially crafted URL can cause an XSS flaw resulting in an attacker being able to execute arbitrary javascript on the victim's browser. An attacker can phish an authenticated user to trigger this vulnerability.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 💎RubyGems | rails_admin | all versions | 1.3.0 |

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 1.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-pxr8-w3jq-rcwj 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-pxr8-w3jq-rcwj 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-pxr8-w3jq-rcwj. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
