CVE-2022-42809

Code execution via crafted Grapher file

Published Nov 1, 2022 · Updated Apr 22, 2025

Memory corruption in Grapher in Apple macOS before 13 allows attackers to crash the app or execute arbitrary code via a crafted .gcx file. Grapher mishandles memory while parsing untrusted .gcx content; Apple has not disclosed the exact parser operation or memory-safety failure. Exploitation requires a user to open or otherwise process the file, and successful code execution runs in the affected application context.
