Endpoint Vulnerability

Improper state in HTML5 Tree Builder with templates

Description

Using the Address Sanitizer tool, security researcher Atte Kettunen from OUSPG found that the HTML5 Tree Builder does not properly store state when interacting with template elements. Because some stack information is incorrectly stored, the template insertion mode stack can be used when it is empty. This could possibly lead to code execution in some circumstances.
