A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sequoia 15.7.2, macOS Tahoe 26.1. An app may be able to access sensitive user data.
The following code is for security research and authorized testing only.
python
// CVE-2025-43378 PoC Concept (Educational Purpose Only)
// This is a conceptual demonstration of the vulnerability pattern
// Actual exploitation requires specific macOS environment and version
// Simulated malicious application behavior
class SensitiveDataAccess {
// Attempt to access protected user data directories
static func exploitVulnerability() {
// Target sensitive directories
let sensitivePaths = [
"~/Library/Application Support/",
"~/Library/Personal/",
"/Library/Application Support/",
"~/Documents/Sensitive/"
]
// Attempt to bypass permission checks
for path in sensitivePaths {
// In vulnerable versions, this may succeed without proper authorization
let data = readProtectedData(path: path)
if data != nil {
// Successfully accessed sensitive data
exfiltrateData(data)
}
}
}
static func readProtectedData(path: String) -> Data? {
// Bypass mechanism exploiting CVE-2025-43378
// The actual exploit would use specific macOS API abuse
return nil
}
static func exfiltrateData(_ data: Data) {
// Data exfiltration logic
// Would send sensitive data to attacker-controlled server
}
}
// Attack execution requires:
// 1. User interaction to install the malicious app
// 2. macOS version prior to security update
// 3. Social engineering to gain user trust
