Typora v1.0.0 through v1.7 version (below) Markdown editor has a cross-site scripting (XSS) vulnerability, which allows attackers to execute arbitrary code by uploading Markdown files.
Cross Site Scripting (XSS) vulnerability in Typora v.1.6.7 and before, allows a local attacker to obtain sensitive information via a crafted script during markdown file creation.
An issue in Typora v.1.8.10 and before, allows a local attacker to obtain sensitive information and execute arbitrary code via a crafted payload to the src component.
Improper path handling in Typora before 1.7.0-dev on Windows and Linux allows a crafted webpage to access local files and exfiltrate them to remote web servers via "typora://app/typemark/". This vulnerability can be exploited if a user opens a malicious markdown file in Typora, or copies text from a malicious webpage and paste it into Typora.
