CVE-2024-26131

Account takeover via unchecked nested intent launch

Published Feb 20, 2024 · Updated Aug 1, 2024

Intent redirection in Element Android 1.4.3 through 1.6.10 allows attackers to launch arbitrary internal activities via a crafted intent. MainActivity reads EXTRA_NEXT_INTENT and passed the nested intent to startActivity without verifying its resolved package or activity class. Exploitation requires a malicious third-party application on the same phone and can open attacker-chosen web content, execute JavaScript, bypass the PIN, or present a credential-stealing login flow.
