CVE-2022-26726 is a vulnerability in Apple macOS (Catalina, Big Sur, Monterey) and watchOS that allowed a malicious application to capture the user's screen without proper authorization. The issue was due to insufficient checks in the affected operating systems, which could be exploited by a local app to bypass privacy controls and access screen contents.

This repository provides a proof-of-concept (POC) exploit for CVE-2022-26726, a vulnerability in macOS (tested on versions 10.15.7, 11.6.1, 12.0, 12.3, and 12.3.1) that allows a local attacker to bypass TCC (Transparency, Consent, and Control) privacy preferences for screen recording. The exploit consists of a shell script (src/POC.sh) and an Objective-C program (src/screenshot.m). The shell script copies the compiled screenshot binary, executes it, and deletes the copy while it is running. This sequence exploits a flaw in macOS's permission checking, allowing the process to take a screenshot of all visible windows without prompting the user for permission. The screenshot is saved as 'screenshot.png' in the same directory. The exploit is local and requires code execution on the target system. The repository is structured with a README.md explaining the vulnerability and usage, a shell script to trigger the exploit, and the Objective-C source code for the screenshot utility.
