Real-World Exposure
melisplatform/melis-cms-sliderReal-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
File upload leading to remote code execution (RCE) in the “melis-cms-slider” module of Melis Technology's Melis Platform. This vulnerability allows an attacker to upload a malicious file via a POST request to '/melis/MelisCmsSlider/MelisCmsSliderDetails/saveDetailsForm' using the 'mcsdetail_img' parameter.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for melisplatform/melis-cms-slider, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update melisplatform/melis-cms-slider to 5.3.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-10353 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-10353 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-10353. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
