CWE	CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
OWASP	A07:2017 - Cross-Site Scripting (XSS)
Confidence Level	Low
Impact Level	Medium
Likelihood Level	Low

Description

The template uses the '| safe' filter in Flask to disable autoescaping, which allows raw HTML to be rendered. If any user-supplied data is passed through this filter, it can lead to cross-site scripting (XSS) vulnerabilities.

Impact

If exploited, an attacker could inject malicious scripts into the page, allowing them to steal user data, hijack sessions, or perform actions on behalf of users. This can compromise user accounts and damage the application's reputation.
