Real-World Exposure
platform/frameworks/base📦platform/frameworks/base📦platform/frameworks/base📦platform/frameworks/base📦platform/frameworks/base📦platform/frameworks/baseReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Android packages — download data is not available via public APIs for these ecosystems.
Description
In shouldHideDocument of ExternalStorageProvider.java, there is a possible bypass of a file path filter designed to prevent access to sensitive directories due to incorrect unicode normalization. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for platform/frameworks/base, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update platform/frameworks/base to 15-next:2025-03-01 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-43093 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.
