Which packages are affected by GHSA-2374-6cvw-qmx6?

GHSA-2374-6cvw-qmx6 affects the following packages: Dnn.Platform (NuGet). Ecosystems affected: NuGet.

How do I fix GHSA-2374-6cvw-qmx6?

Update Dnn.Platform to 10.1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2374-6cvw-qmx6 is resolved across your whole dependency graph.

How do I detect GHSA-2374-6cvw-qmx6 in my NuGet dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Dnn.Platform. 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.

How do I mitigate GHSA-2374-6cvw-qmx6 if there is no patch (or I can't update yet)?

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 does O3 Security protect against GHSA-2374-6cvw-qmx6?

O3 pinpoints whether GHSA-2374-6cvw-qmx6 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-2374-6cvw-qmx6 actively exploited in the wild?

No public exploit code has been indexed for GHSA-2374-6cvw-qmx6 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 GHSA-2374-6cvw-qmx6?

GHSA-2374-6cvw-qmx6 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 9th 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 GHSA-2374-6cvw-qmx6?

GHSA-2374-6cvw-qmx6 is classified as Unrestricted File Upload (CWE-434), CWE-1188 (CWE-1188). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-2374-6cvw-qmx6 published, and has it been updated?

GHSA-2374-6cvw-qmx6 was published on October 29, 2025 and was last updated on October 29, 2025. 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 NuGet packages — download data is not available via public APIs for these ecosystems.

Description

Summary

The out-of-box experience for HTML editing allows unauthenticated users to upload files. This opens a potential vector to other security issues and is not needed on most implementations.

Details

The new out-of-box experience blocks that endpoint to unauthenticated users. If there is a real need for the implementation to allow unauthenticated uploads, then the web.config can be edited by the implementer to remove that block and open the endpoint to the public.
