Blast Radius
melisplatform/melis-asset-managerReal-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
MelisAssetManager provides deliveries of Melis Platform's assets located in every module's public folder. Attackers can read arbitrary files on affected versions of melisplatform/melis-asset-manager, leading to the disclosure of sensitive information. Conducting this attack does not require authentication. Users should immediately upgrade to melisplatform/melis-asset-manager >= 5.0.1. This issue was addressed by restricting access to files to intended directories only.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for melisplatform/melis-asset-manager. 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.
Fix
Update melisplatform/melis-asset-manager to 5.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-39296 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.
How O3 protects you
O3 pinpoints whether CVE-2022-39296 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2022-39296. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
