Name of the Vulnerable Software and Affected Versions Typora versions prior to 1.7.0-dev

Description The issue is related to improper path handling, which allows a crafted webpage to access local files and exfiltrate them to remote web servers via "typora://app/typemark/". This can be exploited if a user opens a malicious markdown file in Typora or copies text from a malicious webpage and pastes it into Typora.

Recommendations For versions prior to 1.7.0-dev, update to version 1.7.0-dev or later to resolve the issue. As a temporary workaround, consider avoiding the use of the "typora://app/typemark/" endpoint until a patch is applied. Additionally, users should be cautious when opening markdown files from untrusted sources or copying text from potentially malicious webpages.
