CVE-2026-28915 is a local privilege escalation vulnerability in CUPS on macOS caused by a parsing flaw in the handling of directory paths. Improper validation of directory path input could allow an application to exploit path handling logic and reach privileged operations in an unintended manner. Apple addressed the issue with improved path validation. The vulnerability affects macOS Sonoma, macOS Sequoia, and macOS Tahoe prior to the fixed releases macOS Sonoma 14.8.7, macOS Sequoia 15.7.7, and macOS Tahoe 26.5.
