CVE-2026-28878 is a privacy vulnerability in Apple Crash Reporter that allowed a local application to enumerate apps installed on a user’s device. The issue affected multiple Apple platforms, including iOS, iPadOS, macOS, tvOS, visionOS, and watchOS. Apple described the flaw as a privacy issue and stated it was addressed by removing sensitive data, indicating that Crash Reporter exposed information that should not have been available to ordinary apps. Successful exploitation did not require code execution in a privileged context; instead, a malicious app could query or infer installed-application inventory from data exposed by the vulnerable component.
