How severe is CVE-2024-5165?

CVE-2024-5165 has a CVSS score of 6.5/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2024-5165?

CVE-2024-5165 affects the following packages: org.eclipse.ditto:ditto (Maven), org.eclipse.ditto:ditto (Maven). Ecosystems affected: Maven.

How do I fix CVE-2024-5165?

Update org.eclipse.ditto:ditto to 3.4.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-5165 is resolved across your whole dependency graph.

How do I detect CVE-2024-5165 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.eclipse.ditto:ditto, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2024-5165 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-2024-5165 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-5165 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-2024-5165?

CVE-2024-5165 has an EPSS (Exploit Prediction Scoring System) score of 0.5%, placing it in the 43th 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-2024-5165?

CVE-2024-5165 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-2024-5165 published, and has it been updated?

CVE-2024-5165 was published on May 23, 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.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

Several inputs were not persisted at the backend of Eclipse Ditto, but only in local browser storage to save settings of "environments" of the UI and e.g. the last performed "search queries", resulting in a "Reflected XSS" vulnerability.

However, several other inputs were persisted at the backend of Eclipse Ditto, leading to a "Stored XSS" vulnerability. Those mean that authenticated and authorized users at Eclipse Ditto can persist Things in Ditto which can - when being displayed by other users also being authorized to see those Things in the Eclipse Ditto UI - cause scripts to be executed in the browser of other users.

Frequently Asked Questions

In Eclipse Ditto starting in version 3.0.0 and prior to versions 3.4.5 and 3.5.6, the user input of several input fields of the Eclipse Ditto Explorer User Interface https://eclipse.dev/ditto/user-interface.html was not properly neutralized and thus vulnerable to both Reflected and Stored XSS (Cross Site Scripting). Several inputs were not persisted at the backend of Eclipse Ditto, but only in local browser storage to save settings of "environments" of the UI and e.g. the last performed "search queries", resulting in a "Reflected XSS" vulnerability.
