Which packages are affected by GHSA-hmvq-8p83-cq52?

GHSA-hmvq-8p83-cq52 affects the following packages: DotNetNuke.Core (NuGet). Ecosystems affected: NuGet.

How do I fix GHSA-hmvq-8p83-cq52?

Update DotNetNuke.Core to 10.1.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hmvq-8p83-cq52 is resolved across your whole dependency graph.

How do I detect GHSA-hmvq-8p83-cq52 in my NuGet dependencies?

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

How do I mitigate GHSA-hmvq-8p83-cq52 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-hmvq-8p83-cq52?

O3 pinpoints whether GHSA-hmvq-8p83-cq52 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-hmvq-8p83-cq52 actively exploited in the wild?

No public exploit code has been indexed for GHSA-hmvq-8p83-cq52 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-hmvq-8p83-cq52?

GHSA-hmvq-8p83-cq52 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 5th 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-hmvq-8p83-cq52?

GHSA-hmvq-8p83-cq52 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 GHSA-hmvq-8p83-cq52 published, and has it been updated?

GHSA-hmvq-8p83-cq52 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.

Description

Summary

Sanitization of the content of uploaded SVG files was not covering all possible XSS scenarios.

Details

DNN validates the contents of SVG's to ensure they are valid and do not contain any malicious code. These checks were introduced as part of CVE-2025-48378.

However, the checks to ensure there are no script elements within the SVG files are not comprehensive and may allow some malicious SVG files to be uploaded.

As this vulnerability allows for the execution of arbitrary JavaScript code within the context of the user's browser, it can lead to a range of attacks, including data exfiltration, session hijacking, and defacement of the web application to name a few.
