CVE-2022-22662Network attack vector

Sensitive information disclosure via cookie state handling

Published May 26, 2022 · Updated Aug 3, 2024

Information disclosure in Apple macOS before the documented security updates allows remote attackers to obtain sensitive user information by processing maliciously crafted web content. WebKit mishandles cookie state during that processing, and Apple describes the correction only as improved state management without publishing a more specific code locus. The attack requires victim interaction with crafted web content; the disclosed impact is confidentiality only, with no reported integrity or availability effect.
