How severe is CVE-2024-24558?

CVE-2024-24558 has a CVSS score of 8.2/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by CVE-2024-24558?

CVE-2024-24558 affects the following packages: @tanstack/react-query-next-experimental (npm). Ecosystems affected: npm.

How do I fix CVE-2024-24558?

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 CVE-2024-24558 is resolved across your whole dependency graph.

How do I detect CVE-2024-24558 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @tanstack/react-query-next-experimental, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-24558 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2024-24558 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-24558 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-24558?

CVE-2024-24558 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 33th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-24558?

CVE-2024-24558 is classified as Cross-site Scripting (XSS) (CWE-79). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2024-24558 published, and has it been updated?

CVE-2024-24558 was published on January 30, 2024 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

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.
