HIGHImproper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in view_component
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
This is an XSS vulnerability that has the potential to impact anyone using translations with the view_component gem. Data received via user input and passed as an interpolation argument to the translate method is not properly sanitized before display.
Versions 2.29.1 and 2.49.1 have been released and fully mitigate the vulnerability.
Avoid passing user input to the translate function, or sanitize the inputs before passing them.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for view_component. 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 view_component to 2.31.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-cm9w-c4rj-r2cf 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-cm9w-c4rj-r2cf 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-cm9w-c4rj-r2cf. 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-cm9w-c4rj-r2cf in your dependencies?
O3 detects GHSA-cm9w-c4rj-r2cf across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
