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.
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.
Typora through 1.3.8 allows XSS if a document containing an SVG element with an attacker-controlled onload attribute is exported and then used at a victim's origin.
