CVE-2026-78196: Path Traversal in achorein expo-share-intent
CVE-2026-78196 is a path traversal vulnerability in the achorein expo-share-intent component affecting version 8.0.0. The flaw exists in the getDataColumn function of ExpoShareIntentModule.kt, where manipulation of the _display_name argument allows path traversal. The vulnerability requires local access to exploit. Upgrading to version 8.0.1 mitigates this issue.
AI Analysis
Technical Summary
This vulnerability involves a path traversal flaw in the Android File Copy Routine of the expo-share-intent component by achorein. Specifically, the getDataColumn function in ExpoShareIntentModule.kt improperly handles the _display_name argument, enabling an attacker with local access to manipulate file paths. This could potentially allow unauthorized file access or modification. The issue affects version 8.0.0 and is resolved in version 8.0.1 with the patch identified by commit c6900b1ed06fcc3ca4b09651348974ac5b95e4e6.
Potential Impact
The vulnerability allows an attacker with local access to perform path traversal via the _display_name argument, potentially leading to unauthorized file access or modification within the affected component. The CVSS score of 4.8 indicates a medium severity impact with local attack vector and low privileges required.
Mitigation Recommendations
Upgrade the expo-share-intent component to version 8.0.1 or later to apply the official patch that fixes this path traversal vulnerability. No other mitigation is indicated or required by the vendor advisory.
