Executive Summary

CVE-2026-30285 is an arbitrary file overwrite vulnerability in the Zora: Post, Trade, Earn Crypto app version 2.60.0. It occurs due to insufficient security validation during the file import process, which allows an attacker to manipulate the filename and content of imported files.

By exploiting path traversal techniques, a malicious app can overwrite critical internal files within the app’s internal storage. This flaw is located in the component co.ourzora.app.MainActivity.

Detection Guidance

Detection of the CVE-2026-30285 vulnerability involves monitoring the file import process within the Zora: Post, Trade, Earn Crypto app (version 2.60.0) for suspicious activity, especially attempts to manipulate filenames or use path traversal techniques to overwrite internal files.

Since the vulnerability exploits file import and path traversal, commands or tools that monitor file system changes or scan for unusual file paths in the app's internal storage could help detect exploitation attempts.

• Use file integrity monitoring tools to detect unexpected changes in critical internal files of the app.
• Monitor logs for unusual file import activities or errors related to file handling in the app.
• On a rooted or development device, commands like 'inotifywait' (Linux) can watch for file changes in the app's internal directories.
• Use 'adb shell' commands to inspect the app's internal storage for unexpected or suspicious files or modifications.

Mitigation Strategies

Immediate mitigation steps include restricting or disabling the file import functionality in the affected app version to prevent exploitation.

Ensure that only trusted sources are allowed to import files and validate filenames to prevent path traversal attacks.

Update the app to a patched version once available from the vendor that fixes the arbitrary file overwrite vulnerability.

Limit app permissions and isolate the app environment to reduce the impact of potential exploitation.
