CVE-2025-43290

Protected file modification via incorrect CoreServices permissions

Published May 26, 2026 · Updated May 26, 2026

macOS Sonoma before 14.8, Sequoia before 15.7, and Tahoe before 26 allows local users to modify protected file-system content. Apple identifies CoreServices as the locus but discloses only that its permission restrictions are insufficient; the affected resource and operation are not public. Exploitation requires a locally executed app with low privileges and permits protected file-system changes, with no reported confidentiality or availability impact.
