CVE-2023-32418

Code execution via crafted file processing

Published Jul 27, 2023 · Updated Oct 23, 2024

Code execution in Grapher in Apple macOS allows attackers to execute arbitrary code or crash the app by processing a crafted file. Apple identifies the locus as Grapher but discloses only that file-processing checks were insufficient, without naming the parser, file format, or faulty operation. Opening or importing an attacker-controlled file is required; successful exploitation runs code in Grapher's user context, while failure can terminate the app.
