Developers urged to update Unity-built apps after mobile security flaw fixed
Unity Technologies has released a critical security patch addressing a vulnerability in Android-based Unity applications that could have allowed the execution of malicious code on user devices. The flaw, discovered in June 2025, raised concerns among cybersecurity experts due to its potential impact on both mobile gamers and crypto users.
The company confirmed that the issue has now been resolved and emphasized there is no evidence of active exploitation. According to a Unity spokesperson, the vulnerability “could have allowed access to confidential data on end-user devices running Unity-built applications,” but added that no user information or system integrity had been compromised.
“Unity has acted swiftly to patch the vulnerability. Developers should immediately download the latest Unity Editor update and rebuild their games to ensure users are protected,” said one cybersecurity researcher familiar with the patch.
Technical reports indicate the bug affected Unity projects dating back to 2017, impacting not only Android but also Windows, macOS, and Linux environments. The flaw potentially allowed malicious local applications to hijack permissions from legitimate Unity apps, which could then be exploited remotely to execute unauthorized code.
Microsoft has since issued a separate advisory confirming that Windows-based Unity games are being updated, while console versions remain unaffected. Additionally, Windows Defender and Android’s anti-malware systems have received new protection definitions to mitigate any lingering threats.
“This is a wake-up call for mobile and game developers. Even a small oversight in engine-level security can expose millions of users, especially those using apps linked to financial services or crypto wallets,” noted BITX senior security analyst.
Unity powers more than 70% of top mobile games worldwide, making this patch one of the most significant in recent years for the gaming ecosystem. Experts recommend all developers rebuild and republish affected titles promptly to ensure full protection for players.
