CVE-2026-30286

Code execution via traversed import filenames

Published Mar 31, 2026 · Updated Mar 31, 2026

Path traversal in Funambol Zefiro Cloud 32.0.2026011614 allows attackers to overwrite internal app files through file import. The com.funambol.a2a.share.ui.A2AReceiveShareActivity component accepts an attacker-controlled filename and content without preventing traversal into internal storage. A malicious app must be opened on the same Android device; it can then corrupt configuration or executable files, causing a crash or arbitrary code execution.
