Improper path handling in Obsidian desktop before 1.2.8 on Windows, Linux and macOS allows a crafted webpage to access local files and exfiltrate them to remote web servers via "app://local/<absolute-path>". This vulnerability can be exploited if a user opens a malicious markdown file in Obsidian, or copies text from a malicious webpage and paste it into Obsidian.
An issue discovered in Obsidian Canvas 1.1.9 allows remote attackers to send desktop notifications, record user audio and other unspecified impacts via embedded website on the canvas page.
