CVE-2023-37450Known exploitationNetwork attack vector

Arbitrary code execution via unspecified WebKit checks

Published Jul 26, 2023 · Updated Oct 21, 2025

Code execution in Apple WebKit products allows remote attackers to run arbitrary code by processing crafted web content. Apple identifies only inadequate WebKit checks and has not published the checked data, code path, or failing operation. Exposure requires WebKit to process attacker-controlled content, and CISA confirms exploitation in the wild.
