There is an ambiguity between strings used e.g., as URLs and font-faces which is problematic, Requiring values that are not simple numbers or keywords to be explicitly wrapped in a type that specifies them as such makes things easier. It was prohibitively expensive to do this automatically for you for any given value.When we last evaluated it, we found that: #3473 We’ve already evaluated and decided against protecting against invalid styles. To respond in particular to the ones you mentioned: Recognition that script element bodies and style attributes are risky value sinks.I dislike this approach because it pushes XSS safety onto the application developer. Proposed new syntax to allow authors to specify sinks known to receive only trusted values.Like tainting, it’s a binary decision, not a decision to trust in a specific set of contexts a la mentions a similar mechanism for explicit // explicitly React.createElement the POJO I believe this is widespread across versions.Īn earlier REPL I tried showed that it worked on version 16.2.0 from but I don’t know what version the jsfiddle above Thanks for the pointers. Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React? They shouldn’t have to either since it is an implementation detail. Many developers know that is risky, but if the link is an implementation detail of a custom React element, then developers don’t have the context to know which attributes they need to be careful with. It allows values to reach browser builtins when they are innocuous or have a runtime type that indicates that the author intentionally marked them as safe for that kind of browser builtin.įor example, an instanceof SafeURL would be allowed to reach as would any string that is a relative URL, or one with a whitelisted protocol in ( http, https, mailto, tel) but not javascript. Polymer Resin uses hooks in another webcomponents framework to intercept value before they reach browser builtins where they can be vetted. #Stringscan code#You should see a blue “link” in the bottom-right pane.Ī simple string that reaches an href attribute should not cause arbitrary code execution even with user interaction.Ī string that reaches a browser builtin like the setter should not cause code execution.After the REPL loads, click the “Run” button at the top left.Load the code above in the codepen REPL.Paste the link to your JSFiddle ( ) or CodeSandbox ( ) example below: Your bug will get fixed much faster if we can run your code and it doesn’t have dependencies other than React. If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. What is the current behavior? var x = 'javascript:alert(1)' Stringscan has not been rated by our users yet.Do you want to request a feature or report a bug?Ī bug, but a well known and worked-around one. Stringscan runs on the following operating systems: Windows. It was initially added to our database on. The latest version of Stringscan is 1.1, released on. #Stringscan software#Stringscan is a Shareware software in the category System Utilities developed by WordTech Communications LLC. More intuitive than other dedicated search tools that feature an overwhelming variety of options and/or a complex interface.įaster than searching from command-line then opening file in separate program to locate search terms within file. Simpler than command-line tools with multiple search options. Using an elegant, intuitive interface, Stringscan allows you to select a directory, specify the search term, and see both the file results and the highlighted term in the file quickly. Stringscan is a simple but powerful application for recursively searching a directory for a specific string of text. Elegant Search for Text in Multiple Directories
