Python supports format from 2.6, a new, easier-to-read string formatting method that changes from the original% mode to a new, more readable The curly braces declare {}, the parameter reference declaration before the render, and the curly brackets can use numbers to denote the ordinal of the reference parameter, or the variable name to refer directly.

The recent vulnerability of a Python string format has caused my attention, and today it is a deep analysis of the security vulnerabilities of a new syntax for formatting strings introduced by Python, and provides a corresponding security solution. When we use Str.format for untrusted user input, there will be a secur

the Python string is formatted using the "character% format 1% format 2 characters"% (variable 1, variable 2), and the% format represents the type of the accepted variable. Simple examples of use are as follows# Example: String fo

In this paper, we analyze the security vulnerabilities of a new type of syntax introduced in Python development, and provide the corresponding security solutions.When we use Str.format for untrusted user input, there will be a security risk-and I know for sure, but until today I am really aware of its seriousness. Because an attacker can use it to bypass the JINJA2 sandbox, this can cause serious information disclosure problems. At the same time, I ha
