CVE-2025-43362 is a critical security vulnerability identified in Apple’s iOS and iPadOS platforms, allowing malicious applications to monitor keystrokes without requiring user permission. The root cause lies in insufficient permission checks that previously allowed apps to capture keyboard input covertly. This vulnerability is categorized under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The issue affects all versions prior to iOS 18.7 and iPadOS 18.7, as well as iOS 26 and iPadOS 26, where Apple introduced enhanced permission validation mechanisms to prevent unauthorized keystroke monitoring. The CVSS v3.1 base score of 9.8 reflects the vulnerability’s critical nature, with attack vector being network-based (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction needed (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). This means an attacker can remotely exploit this flaw without any user involvement or elevated permissions, enabling them to capture sensitive input such as passwords, personal messages, or confidential data entered via the keyboard. Although no active exploits have been reported in the wild, the vulnerability’s characteristics make it a prime target for attackers seeking to conduct espionage, data theft, or surveillance on Apple mobile device users. The fix involves improved permission checks that explicitly prevent apps from accessing keystroke data without explicit user consent, thereby closing the unauthorized monitoring vector.

The potential impact of CVE-2025-43362 is severe for organizations and individuals relying on Apple iOS and iPadOS devices. Unauthorized keystroke monitoring can lead to the exposure of highly sensitive information, including passwords, authentication tokens, private communications, and confidential business data. This compromises user privacy and can facilitate further attacks such as account takeover, identity theft, corporate espionage, and unauthorized data exfiltration. The integrity of user input is also at risk, as attackers could potentially manipulate input data or inject malicious commands. Availability could be indirectly affected if attackers leverage captured credentials to disrupt services or lock users out of their accounts. Given the widespread use of Apple mobile devices in enterprise, government, healthcare, and personal contexts, the vulnerability poses a global risk to data security and user trust. The ease of exploitation without user interaction or privileges increases the likelihood of rapid and widespread abuse if the vulnerability is weaponized.

To mitigate the risk posed by CVE-2025-43362, organizations and users should immediately update all affected Apple devices to iOS 18.7, iPadOS 18.7, iOS 26, or iPadOS 26, where the vulnerability has been patched with improved permission checks. Beyond patching, organizations should enforce strict app vetting policies, only allowing apps from trusted sources such as the official Apple App Store, and monitor app permissions regularly to detect any suspicious access attempts. Employ Mobile Device Management (MDM) solutions to control app installations and permissions centrally. Users should be educated about the risks of installing apps from unknown developers and encouraged to review app permissions carefully. Additionally, implementing multi-factor authentication (MFA) can reduce the impact of credential compromise resulting from keystroke monitoring. Network-level protections such as anomaly detection and endpoint monitoring can help identify unusual behaviors indicative of exploitation attempts. Finally, organizations should maintain an incident response plan that includes steps for addressing potential data breaches stemming from this vulnerability.
