Ibexa Kernel's files with blacklisted extensions can be still saved to draftsGHSA-mwvh-p3hx-x4gg
Fix: ezsystems/ezplatform-kernel@7e47231GHSA-mwvh-p3hx-x4gg is a security vulnerability in ezsystems/ezplatform-kernel. A fix is available for ezsystems/ezplatform-kernel — see the affected versions and patch details below.
Real-World Exposure
ezsystems/ezplatform-kernelReal-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.

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
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.
Workarounds
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.
