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

Detected a template variable used as the 'src' in a script tag. Although template variables are HTML escaped, HTML escaping does not always prevent malicious URLs from being injected and could results in a cross-site scripting (XSS) vulnerability. Prefer not to dynamically generate the 'src' attribute and use static URLs instead. If you must do this, carefully check URLs against an allowlist and be sure to URL-encode the result.
