CVE-2025-31213 is a vulnerability identified in Apple iPadOS and several macOS versions that allows an application to access usernames and associated websites stored in a user's iCloud Keychain. The root cause is a logging issue where sensitive data was not properly redacted, leading to exposure of credential metadata. This vulnerability falls under CWE-532, which relates to information exposure through log files. The flaw was addressed by Apple in iPadOS 17.7.7, macOS Sequoia 15.5, macOS Sonoma 14.7.6, and macOS Ventura 13.7.6 through improved data redaction techniques. The CVSS v3.1 score is 7.6, indicating high severity, with the vector AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L, meaning the attack can be performed remotely over the network with low attack complexity, requires low privileges, no user interaction, and impacts confidentiality highly, with limited impact on integrity and availability. No known exploits are currently in the wild. The vulnerability allows an attacker who can run an app on the device to extract sensitive metadata about stored credentials, potentially facilitating further attacks such as credential stuffing or phishing. This issue is particularly critical because iCloud Keychain is used to securely store passwords and other sensitive data, and leakage of this metadata undermines user privacy and security.

The primary impact of CVE-2025-31213 is the unauthorized disclosure of usernames and associated websites stored in iCloud Keychain, compromising user confidentiality. This exposure can lead to targeted credential-based attacks, including phishing, credential stuffing, or social engineering. Organizations relying on Apple devices for secure credential storage may face increased risk of account compromise and data breaches. The vulnerability also affects system availability and integrity to a lesser extent, as indicated by the CVSS vector, but the main concern is data leakage. Since exploitation requires only low privileges and no user interaction, malicious apps or insiders could leverage this flaw to gather sensitive information stealthily. This could be particularly damaging in environments where Apple devices are used to manage critical infrastructure, sensitive communications, or intellectual property. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits following public disclosure. The vulnerability also undermines user trust in Apple's security model, potentially affecting enterprise adoption and compliance with data protection regulations.

To mitigate CVE-2025-31213, organizations and users should promptly apply the security updates released by Apple for iPadOS 17.7.7 and the specified macOS versions (Sequoia 15.5, Sonoma 14.7.6, Ventura 13.7.6). Beyond patching, organizations should implement strict app vetting and restrict installation of apps to trusted sources only, minimizing the risk of malicious apps exploiting this vulnerability. Employ Mobile Device Management (MDM) solutions to enforce app permission policies and monitor for anomalous app behavior that could indicate exploitation attempts. Additionally, educate users about the risks of installing untrusted applications and encourage the use of strong, unique passwords combined with multi-factor authentication to reduce the impact of credential exposure. Regularly audit logs and system behavior for signs of unauthorized access to keychain data. For high-security environments, consider limiting the use of iCloud Keychain or employing alternative credential management solutions with enhanced security controls. Finally, maintain an incident response plan that includes steps for credential compromise scenarios to quickly contain and remediate any breaches.
