Comprehensive Technical Analysis of CVE-2025-31255

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-31255

Description: An authorization issue was addressed with improved state management. This issue is fixed in tvOS 26, macOS Sonoma 14.8, macOS Sequoia 15.7, watchOS 26, macOS Tahoe 26, iOS 26, and iPadOS 26. An app may be able to access sensitive user data.

CVSS Score: 9.8

Severity Evaluation: The CVSS score of 9.8 indicates a critical vulnerability. This high score is likely due to the potential for unauthorized access to sensitive user data, which can have severe implications for user privacy and security.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Malicious Apps: An attacker could develop a malicious app that exploits the authorization issue to access sensitive user data.
• Compromised Apps: Legitimate apps with vulnerabilities could be exploited to gain unauthorized access to user data.
• Phishing: Users could be tricked into installing malicious apps or granting excessive permissions to legitimate apps.

Exploitation Methods:

• Privilege Escalation: An attacker could use the vulnerability to escalate privileges within the app, allowing access to sensitive data.
• Data Exfiltration: Once access is gained, the attacker could exfiltrate sensitive data such as personal information, credentials, or financial data.
• Persistent Access: The attacker could maintain persistent access to the user's data by exploiting the vulnerability repeatedly.

3. Affected Systems and Software Versions

Affected Systems:

• tvOS 26
• macOS Sonoma 14.8
• macOS Sequoia 15.7
• watchOS 26
• macOS Tahoe 26
• iOS 26
• iPadOS 26
