Vulnerabilities

BlueStacks 4.80.0.1060 contains a denial of service vulnerability that allows local attackers to crash the application by submitting oversized input to the search field. Attackers can paste a buffer of 100,000 'A' characters into the search field and trigger a search operation to cause the application to crash.

A lack of SSL certificate validation in BlueStacks v5.20 allows attackers to execute a man-it-the-middle attack and obtain sensitive information.

Incorrect file permissions in BlueStacks 4 through 4.230 on Windows allow a local attacker to escalate privileges by modifying a file that is later executed by a higher-privileged user.

An issue was discovered in BlueStacks 4.110 and below on macOS and on 4.120 and below on Windows. BlueStacks employs Android running in a virtual machine (VM) to enable Android apps to run on Windows or MacOS. Bug is in a local arbitrary file read through a system service call. The impacted method runs with System admin privilege and if given the file name as parameter returns you the content of file. A malicious app using the affected method can then read the content of any system file which it is not authorized to read

BlueStacks App Player 2, 3, and 4 before 4.90 allows DNS Rebinding for attacks on exposed IPC functions.

BlueStacks App Player (BlueStacks App Player for Windows 3.0.0 to 4.31.55, BlueStacks App Player for macOS 2.0.0 and later) allows an attacker on the same network segment to bypass access restriction to gain unauthorized access.

A local privilege escalation vulnerability exists in BlueStacks App Player. The BlueStacks App Player installer creates a registry key with weak permissions that allows users to execute arbitrary programs with SYSTEM privileges.
