IdentifiersCVE-2025-24221CWE-200

CVE-2025-24221 is an Apple vulnerability in the Accounts component affecting visionOS, iOS, and iPadOS. According to the provided advisory text, sensitive keychain data may be accessible from an iOS backup. Apple states the issue was addressed with improved data access restriction and fixed in visionOS 2.4, iOS 18.4, iPadOS 18.4, and iPadOS 17.7.6. Based on the available information, the flaw is an access control/data protection weakness that allowed keychain material that should remain protected to be exposed through backup data.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation could expose sensitive keychain data to an attacker able to obtain and inspect an affected iOS backup. Depending on the contents of the exposed keychain items, this could result in disclosure of credentials, tokens, secrets, or other protected user data, with possible downstream account compromise or privacy impact.

Mitigation

If you can’t patch tonight, do this now.

Apply the vendor patches as the primary mitigation. Until updates are deployed, reduce exposure by limiting access to device backups, protecting backup storage locations, restricting backup extraction and analysis to trusted administrators, and minimizing creation or retention of unencrypted or broadly accessible backups where operationally feasible. Specific non-patch mitigations beyond backup access control are not provided in the supplied content.

Remediation

Patch, then assume compromise.

Upgrade affected devices to the fixed releases identified by Apple: visionOS 2.4, iOS 18.4, iPadOS 18.4, or iPadOS 17.7.6, as applicable. Apple indicates the issue was remediated by improved data access restriction.
