I want to do an INSERT into a MySQL database using: $sql = "INSERT INTO table (title1) VALUES ('$myVar')"; but the problem is $myVar can contain the single quotes ( ' symbols, e.g. in "idiot's"). Can somebody tell me how to handle any single quotes in the variable as a letter and not as a piece of code? (I know there are posts about this in the forum already, but I do not really

问题 I need to let users enter Markdown content to my web app, which has a Python back end. I don’t want to needlessly restrict their entries (e.g. by not allowing any HTML, which goes against the spirit and spec of Markdown), but obviously I need to prevent cross-site scripting (XSS) attacks. I can’t be the first one with this problem, but didn’t see any SO questions with all the keywords “python,” “Markdown,” and “XSS”, so here goes. What’s a best-practice way to process Markdown and prevent XSS

问题 According to some React documentation: Improper use of the innerHTML can open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet. It seems that improper usage of the sanitizers and the innerHTML can expose the site XSS (Cross-Site Scripting) attacks. On the other hand, according to other documentation (such as Gatsby or sanitizers

问题 Small example, reduced from a REST API node.js app: const { exec } = require('child_process'); var userInput = 'untrusted source'; var cmd = `/bin/echo "${userInput}"`; exec(cmd, function(err, stdout, stderr) { console.log('echo: ' + stdout); }); Assuming the userInput is from an untrusted source, what needs to be done avoid any vulnerability? For example, the quoted "${userInput}" parameter for echo avoids input 'evil spirit; rm -rf /' from causing damage. What else needs to be done to stay

问题 I have following HTML with a property binding: <div [innerHtml]="logOutput"></div> In my component I add now some content with this line of code this.logOutput = this.sanitizer.bypassSecurityTrustHtml( this.logOutput + otpStr ); But nevertheless I get this error "SafeValue must use [property]=binding". Why I get this error? I'm already using property binding! I'm using Angular 5. Edit: I tried out using a custom pipe inside the HTML and it worked fine, but I want a solution without pipes.
