AI Analysis

Impact

An application can bypass required entitlement checks to avoid being recorded by the App Privacy Report, allowing it to collect or transmit data without the privacy safeguard that would normally be enforced. This vulnerability is classified as CWE-863, an Improper Authorization issue, which may lead to privacy violations and unauthorized data exposure. The flaw enables an app to circumvent system‑enforced privacy protections, keeping its data usage hidden from the user’s privacy dashboard.

Affected Systems

Apple iOS and iPadOS devices running versions prior to iOS 18.7.9 and iPadOS 18.7.9, as well as prior to iOS 26.4 and iPadOS 26.4 are affected. The vulnerability is fixed in the 18.7.9/26.4 releases.

Risk and Exploitability

The EPSS score is <1%, indicating a low probability of exploitation, and the vulnerability is not listed in KEV. The CVSS score is 7.5, reflecting high severity. The flaw permits a local or remote application to subvert system‑enforced privacy protections once it is installed. The likely attack vector is inferred to be any app that can install on the device, such as through the App Store or a side‑loaded package; this inference is made because the description references entitlement checks that are enforced at install time and no public exploit is described. Because this is a direct entitlement bypass, an attacker does not require additional privileges beyond those granted to a legitimate application, making the exploitation path clear and potentially accessible to a wide range of malicious apps.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update the device to iOS 18.7.9, iPadOS 18.7.9, iOS 26.4, or iPadOS 26.4, which contain the entitlement check fix.
  • Enforce an update policy that guarantees all managed devices run one of the fixed OS releases, and configure automated update enrollment if available.
  • Configure MDM controls to restrict installation of unauthorized third‑party apps and enable App Privacy Report logging to detect anomalous data collection activities.
