CVE-2021-43419

Payment-card disclosure via sensitive logcat entries

Published Nov 7, 2023 · Updated Sep 5, 2024

Insecure logging in OPay 1.5.1.26 for Android allows attackers with log access to read payment-card details and CVV codes. The application writes sensitive payment-card data, including CVV codes, to Android logcat instead of excluding it from diagnostic output. Exposure requires access to the affected device's logcat output; published evidence does not establish disclosure of other account data.
