GHSA-r3xc-47qg-h929
GHSA-r3xc-47qg-h929 is a security vulnerability in @ionic/core. O3 Security confirms whether GHSA-r3xc-47qg-h929 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Cross-Site Scripting in @ionic/core
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
@ionic/corenpmDescription
Versions of @ionic/core prior to 4.0.3, 4.1.3, 4.2.1 or 4.3.1 are vulnerable to Cross-Site Scripting (XSS). The package uses the unsafe innerHTML function without sanitizing input, which may allow attackers to execute arbitrary JavaScript on the victim's browser. This issue affects the components:
<ion-alert>.message<ion-searchbar>.placeholder<ion-infinite-scroll-content>.loadingText<ion-refresher-content>.pullingText<ion-refresher-content>.refershingText
Recommendation
- If you are using @ionic/core 4.0.x, upgrade to 4.0.3 or later.
- If you are using @ionic/core 4.1.x, upgrade to 4.1.3 or later.
- If you are using @ionic/core 4.2.x, upgrade to 4.2.1 or later.
- If you are using @ionic/core 4.3.x, upgrade to 4.3.1 or later.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @ionic/core. 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 @ionic/core to 4.0.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r3xc-47qg-h929 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-r3xc-47qg-h929 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-r3xc-47qg-h929. 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-r3xc-47qg-h929 in your dependencies?
O3 detects GHSA-r3xc-47qg-h929 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
