def injectCSS_Paths(self, code):

Security Concern: The injectCSS_Paths function currently uses str.replace() to directly inject values, which can become a security risk with untrusted input.

Suggestion: Refactor the replacements using a dictionary to allow for safer and more manageable substitutions.

Code Suggestion:

def injectCSS_Paths(self, code):
    replacements = {
        "[FAVICON_HREF]": self.CSSFiles[0]['src'],
        "[FAVICON_PNG_HREF]": self.CSSFiles[1]['src'],
        "[BASE_ICONS_HREF]": self.CSSFiles[2]['src'],
        "[STYLES_HREF]": self.CSSFiles[3]['src'],
        "[NORMALIZE_HREF]": self.CSSFiles[4]['src'],
        "[SERVICES_ICONS_HREF]": self.CSSFiles[5]['src']
    }
    for placeholder, value in replacements.items():
        code = code.replace(placeholder, value)
    return code
    

Benefit: Using a structured replacement approach makes this function easier to expand and reduces security risks if new replacements are added.
