CVE-2025-30430 is a critical authentication bypass vulnerability affecting Apple’s password autofill mechanism on iOS, iPadOS, visionOS, and macOS Sequoia. The flaw arises from improper state management in the autofill system, allowing passwords to be filled into input fields even after the user has failed authentication, such as Face ID, Touch ID, or passcode verification. This means that an attacker or malicious application could potentially trigger autofill and retrieve stored passwords without proper user authentication, leading to unauthorized credential disclosure. The vulnerability spans multiple Apple platforms and versions prior to iOS 18.4, iPadOS 18.4, visionOS 2.4, and macOS Sequoia 15.4, where the issue has been addressed by Apple. The CVSS 3.1 base score of 9.8 indicates a critical severity, with attack vector being network-based, no privileges or user interaction required, and full impact on confidentiality, integrity, and availability. The CWE-287 classification highlights an authentication bypass weakness. While no active exploitation has been reported, the vulnerability’s nature makes it a high-value target for attackers aiming to harvest credentials silently. The flaw undermines the trust model of Apple’s secure autofill system, potentially exposing users’ passwords to unauthorized parties. Organizations relying on Apple devices for secure authentication and password management must prioritize patching to prevent credential leakage and subsequent attacks such as account takeover or lateral movement within networks.

For European organizations, this vulnerability presents a severe risk to the confidentiality and integrity of user credentials stored on Apple devices. Given the widespread use of iOS and iPadOS devices in business environments across Europe, especially in sectors like finance, healthcare, and government, unauthorized password disclosure could lead to account compromise, data breaches, and disruption of critical services. The ability to bypass authentication without user interaction increases the attack surface, potentially enabling remote attackers to harvest credentials silently. This could facilitate further attacks such as phishing, identity theft, or ransomware deployment. The impact extends to any organization using Apple’s autofill feature for password management, including enterprises with bring-your-own-device (BYOD) policies. The vulnerability also risks undermining user trust in Apple’s security mechanisms, potentially affecting compliance with data protection regulations like GDPR if personal data is exposed. The absence of known exploits in the wild provides a window for mitigation, but the critical severity demands immediate attention to prevent exploitation.

European organizations should immediately update all Apple devices to the patched versions: iOS 18.4, iPadOS 18.4, visionOS 2.4, and macOS Sequoia 15.4 or later. Until updates are deployed, organizations should consider disabling password autofill features on managed devices to reduce risk. Implementing Mobile Device Management (MDM) policies to enforce OS updates and restrict autofill usage can help mitigate exposure. Educate users about the risks of autofill and encourage the use of dedicated password managers with strong authentication controls. Monitor device logs and network traffic for unusual autofill activity or authentication failures. Conduct audits of credential storage and access policies to ensure minimal exposure. Additionally, organizations should review multi-factor authentication (MFA) implementations to reduce the impact of potential credential compromise. Incident response plans should be updated to include scenarios involving credential leakage from device autofill features. Collaboration with Apple support channels for timely vulnerability information and patches is also recommended.
