AI-suggested
To mitigate CVE-2026-20663, organizations and users should promptly update all iOS and iPadOS devices to versions 18.7.5 or 26.3 and later, where the vulnerability is patched. Beyond patching, organizations should enforce strict app installation policies, limiting installation to trusted sources and vetted applications to reduce the risk of malicious apps exploiting this or similar vulnerabilities. Employ Mobile Device Management (MDM) solutions to monitor and control app permissions and detect anomalous app behavior. Additionally, audit and restrict apps that request unnecessary privileges, especially those that could access system logs or device information. Developers should follow best practices for logging, ensuring sensitive information is never exposed in logs. Regular security awareness training for users about the risks of installing untrusted apps can further reduce exposure.
Description
The issue was resolved by sanitizing logging. This issue is fixed in iOS 18.7.5 and iPadOS 18.7.5, iOS 26.3 and iPadOS 26.3. An app may be able to enumerate a user's installed apps.
