Arbitrary file overwrite via unsanitized display name
Published Jul 2, 2026 · Updated Jul 2, 2026
Path traversal in react-native-receive-sharing-intent allows local attackers to overwrite private app files through shared content URIs. FileDirectory.getDataColumn passes attacker-controlled _display_name values directly to File(context.cacheDir, fileName) without basename reduction or canonical-path containment. Exploitation requires a co-resident Android app to send ACTION_SEND to an exported share receiver, enabling writes to databases, preferences, or configuration files.
