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.

Obsidian before 1.2.2 allows calls to unintended APIs (for microphone access, camera access, and desktop notification) via an embedded web page.

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.

Obsidian 0.14.x and 0.15.x before 0.15.5 allows obsidian://hook-get-address remote code execution because window.open is used without checking the URL.

Obsidian Dataview through 0.4.12-hotfix1 allows eval injection. The evalInContext function in executes user input, which allows an attacker to craft malicious Markdown files that will execute arbitrary code once opened. NOTE: 0.4.13 provides a mitigation for some use cases.

Obsidian before 0.12.12 does not require user confirmation for non-http/https URLs.
