“An authenticated attacker may use social engineering to steer a sufferer to obtain and open a specifically crafted file from a web site to trigger an area assault on the sufferer’s laptop. This vulnerability will be exploited.”

Microsoft OneNote for Android is weak to CVE-2023-21823, and note-taking companies are more and more rising as malware distribution vectors, so it is necessary that customers apply the repair.
