sanitize

I'm trying to call sanitize within a controller. Here's what I tried: class FooController < ApplicationController include ActionView::Helpers::SanitizeHelper # ... end However, I'm getting this error: undefined method `white_list_sanitizer' for FooController:Class I searched around and people recommended switching the include line to include ActionView::Helpers , but that results in this error: undefined method `url_for' for nil:NilClass What's the correct way to call sanitize ? I'm using Rails 2.3.5. you can use this ActionController::Base.helpers inside action method: class SiteController <

I'm developing an application using Wordpress as a CMS. I have a form with a lot of input fields which needs to be sanitized before stored in the database. I want to prevent SQL injection, having javascript and PHP code injected and other harmful code. Currently I'm using my own methods to sanitize data, but I feel that it might be better to use the functions which WP uses. I have looked at Data Validation in Wordpress, but I'm unsure on how much of these functions I should use, and in what order. Can anyone tell what WP functions are best to use? Currently I'm "sanitizing" my input by doing

How do I sanitise user input in a bash script so that I can then pass it as an argument to another shell program? I want to prevent the following: INPUT="filename;rm -rf /" ls $INPUT I was thinking it should be enough to surround the user input in double quotes like so: ls "$INPUT" but what if there is a double quote in $INPUT ? Or does bash already deal with this problem? The Short Bash already deals with that. Quoting it is sufficient. ls "$INPUT" The Long A rough guide to how the shell parses this line is: "ls \"$INPUT\"" # Raw command line. ["ls", "\"$INPUT\""] # Break into words. ["ls", "

Using Rails, I need to get a plain text and show it as HTML, but I don't want to use <pre> tag, as it changes the format. I needed to subclass HTML::WhiteListSanitizer to escape non whitelisted tags (by changing process_node ), monkey patch HTML::Node to don't downcase tags' names and monkey patch HTML::Text to apply <wbr /> word splitting: class Text2HTML def self.convert text text = simple_format text text = auto_link text, :all, :target => '_blank' text = NonHTMLEscaper.sanitize text text end # based on http://www.ruby-forum.com/topic/87492 def self.wbr_split str, len = 10 fragment = /.{#

How can we sanitize this? What's up with these unicode characters? That's a character with a series of combining characters . Because the combining

I recently have been moving a bunch of MP3s from various locations into a repository. I had been constructing the new file names using the ID3 tags (thanks, TagLib-Sharp!), and I noticed that I was getting a System.NotSupportedException : "The given path's format is not supported." This was generated by either File.Copy() or Directory.CreateDirectory() . It didn't take long to realize that my file names needed to be sanitized. So I did the obvious thing: public static string SanitizePath_(string path, char replaceChar) { string dir = Path.GetDirectoryName(path); foreach (char c in Path

This question already has an answer here: Angular HTML binding 18 answers I am trying to get third-party (potentially unsafe) html content from my database and insert it into my html document. How do I safely do that (Protection against XSS) ? In Angular1.x there used to be $sce to sanitize input, how do I do that in Angular2 ? As far as I understand, Angular2 automatically sanitizes it by default, is that correct ? Something like this will not work: <div class="foo"> {{someBoundValueWithSafeHTML}} // I want HTML from db here </div> To insert normal HTML into your angular2 app, you can use the

I would like to have the ability to let users submit arbitrary JavaScript code, which is then sent to a Node.JS server and safely executed before the output is sent back to multiple clients (as JSON). The eval function comes to mind, but I know this has multiple security concerns (the user submitted code would be able to access Node's File API, etc). I have seen some projects like Microsoft Web Sandbox and Google Caja which allow execution of sanitized markup and script (for embedding third-party ads on websites), but it seems that these are client-side tools and I'm not sure if they can be
