User input in format string detected.

Description

If an application includes user input directly in a format string, an attacker can use format specifiers in the user input to produce misleading or fabricated messages.

Remediations

❌ Avoid format strings containing user input:

console.log(`The value was ${req.params.value}`)

✅ Use a literal format string with additional arguments:

console.log("The value was %s", req.params.value)
