CVE-2020-3874Network attack vector

Message-content disclosure via flawed screenshot naming

Published Feb 27, 2020 · Updated Aug 4, 2024

Information disclosure in Apple iOS and iPadOS before 13.3.1 allows attackers to read additional Messages content from screenshots. The Screenshots component assigns affected captures names that expose more message content than intended; Apple has not disclosed the faulty naming rule. Exposure requires a screenshot of Messages to be created and made accessible, and the reported consequence is limited to unintended message-content disclosure.
