Which packages are affected by GHSA-mwvh-p3hx-x4gg?

GHSA-mwvh-p3hx-x4gg affects the following packages: ezsystems/ezplatform-kernel (Packagist). Ecosystems affected: Packagist.

How do I fix GHSA-mwvh-p3hx-x4gg?

Update ezsystems/ezplatform-kernel to 1.3.35 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-mwvh-p3hx-x4gg is resolved across your whole dependency graph.

How do I detect GHSA-mwvh-p3hx-x4gg in my Packagist dependencies?

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

How do I mitigate GHSA-mwvh-p3hx-x4gg 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-mwvh-p3hx-x4gg?

O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-mwvh-p3hx-x4gg can be triaged on real exposure rather than presence alone.

Is GHSA-mwvh-p3hx-x4gg actively exploited in the wild?

No public exploit code has been indexed for GHSA-mwvh-p3hx-x4gg 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.

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

Description

Impact

File validation can be configured to reject certain files by file type. When this happens, validation fails, and the content can't be published. However, the file can be saved when saving the content draft. This means unwanted files can be present in storage, even if they are not easily accessible due to the content not being published. The fix ensures these unwanted file types are never stored. An attacker would need to have existing access to create content with a file field type to exploit this.
