Pixel Markup vulnerability allows screenshots to be un-redacted
Besides the Samsung Exynos modem issue, Android 13 QPR2 with the March 2023 security update fixes a vulnerability with the Pixel’s Markup screenshot tool. Dubbed “aCropalypse,” Simon Aarons identified and reported this vulnerability (CVE-2023-21036) to Google in early January, with the initial proof-of-concept exploit developed by David Buchanan: Screenshots cropped using the built-in “Markup” app on Google Pixel devices may be retroactively un-cropped and un-redacted under many circumstances.
