HIGHreact-query-streamed-hydration Cross-site Scripting vulnerability
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
The @tanstack/react-query-next-experimental NPM package is vulnerable to a cross-site scripting vulnerability. To exploit this, an attacker would need to either inject malicious input or arrange to have malicious input be returned from an endpoint.
This vulnerability arises from improper handling of untrusted input when @tanstack/react-query-next-experimental performs server-side rendering of HTML pages. To fix this vulnerability, we implemented appropriate escaping to prevent javascript injection into rendered pages.
Patches
To fix this issue, please update to version 5.18.0 or later.
Workarounds
There are no known workarounds for this issue. Please update to version 5.18.0 or later.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @tanstack/react-query-next-experimental. 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 @tanstack/react-query-next-experimental to 5.18.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-997g-27x8-43rf 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-997g-27x8-43rf 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-997g-27x8-43rf. 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-997g-27x8-43rf in your dependencies?
O3 detects GHSA-997g-27x8-43rf across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
