Lifecycle Timeline
3DescriptionCVE.org
A security flaw has been discovered in achorein expo-share-intent up to 8.0.0. This affects the function getDataColumn of the file ExpoShareIntentModule.kt of the component Android File Copy Routine. The manipulation of the argument _display_name results in path traversal. The attack requires a local approach. Upgrading to version 8.0.1 is able to mitigate this issue. The patch is identified as c6900b1ed06fcc3ca4b09651348974ac5b95e4e6. The affected component should be upgraded.
AnalysisAI
Path traversal in achorein expo-share-intent up to version 8.0.0 allows a local attacker to write files outside the intended cache directory by supplying a crafted _display_name value during Android file sharing operations. The getDataColumn function in ExpoShareIntentModule.kt constructed file paths directly from the unvalidated content-provider display name, enabling directory escape via sequences such as ../../. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a local attacker with the ability to install a malicious application on the same Android device or otherwise control a process capable of issuing a crafted share intent to the target application. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:L) and score of 4.8 accurately reflect the constrained threat model: exploitation is strictly local, requires low privileges, and yields only limited integrity and availability impact with no confidentiality exposure. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A malicious Android application co-installed on the same device constructs a share intent targeting the vulnerable app and sets the `_display_name` content-provider field to a traversal string such as `../../lib/malicious.so`. When the victim app invokes `getDataColumn` to process the shared file, the unsanitized filename is passed to `File(context.cacheDir, fileName)`, causing the received file to be written to an attacker-chosen path outside the cache directory. … |
| Remediation | Upgrade to expo-share-intent version 8.0.1, which incorporates the fix from commit c6900b1ed06fcc3ca4b09651348974ac5b95e4e6 merged via GitHub PR #221 (https://github.com/achorein/expo-share-intent/pull/221); the patched release is published at https://github.com/achorein/expo-share-intent/releases/tag/v8.0.1. … Detailed patch versions, workarounds, and compensating controls in full report. |
