Data validation / Sanitization callback function
By default, the Customizer does not handle validation and sanitization of the user input values. It is therefore essential to sanitize these values before saving them to the database. The add_setting() method of the WP_Customizer object accepts an 'sanitize_callback' argument, that can be used to specify a sanitization callback. So,...
Sanitizing SQL in Rails where conditions may be NULL
sql,ruby-on-rails,activerecord,sanitization
It looks like the error is being thrown in the reset_table_name method at https://github.com/rails/rails/blob/7bb620869725ad6de603f6a5393ee17df13aa96c/activerecord/lib/active_record/model_schema.rb#L160 so maybe this method is not designed to work on the ActiveRecord::Base class. Assuming you have got a model class for Folder this should work: Folder.send(:sanitize_sql_hash, {user_id: current_user.id, parent_id: params[:parent_id]}) In a quick test I got...
Is there a better way to sanitize input with javascript?

Should I implement user data sanitization/validation as middleware?
php,validation,middleware,slim,sanitization
Using global middleware doesn't make sense as you end up coupling every endpoint's parameter list together. The two options I would consider are: Implement as route middleware so that you can have different filtering/validation for each endpoint. e.g. function fooFilter() { // filter/validate GET variables here and set back into...
Sanitize and Highlight Text with HTML at the same time
Sanitize both your data AND the query. Then the sanitized query will still be found in the sanitized HTML data. function sanitize_and_highlight_search_result($data, $query){ $sanitized = sanitize($data); $query = sanitize($query); return str_replace( $query, '<span class="highlight">' . $query .

angular-translate sanitisation fails with UTF characters
javascript,angularjs,sanitization,angular-translate
At the moment, you have two options: Use the strategy sanitizeParameters which will only sanitize the dynamic parameters, but not the actual translation (template).

While you could use AntiSamy to do it, I don't know how sensible that would be. Kinda defeats the purpose of it's flexibility, I think. I'd be curious about the overhead, even if minimal, to running that as a filter over just a regex. Personally I'd probably opt for the...

Try this instead: parse_str($_REQUEST['data'], $v); $v = array_map('trim', $v); If you want to trim whitespace from each element in the query string, first convert your query string to an array with parse_str(), then trim() each resulting element of that array. EDIT Based on one of your comments above, you may...
Can an SQL injection be made with a single word in a SELECT statement?
php,mysqli,sql-injection,sanitization
You can still exploit this using hex coding: stripping spaces is not enough. I guess this is a somewhat interesting place to start. But consider that preg_match()es are pretty bad for performance on high traffic sites. Prepared statements and parameterized queries are always the best way to prevent SQL injections....

Is it safe to unescape ampersand for user input?

If your entities are displayed as text, then you're probably calling htmlspecialchars() twice. If you are not calling htmlspecialchars() twice explicitly, then it's probably a browser-side auto-escaping that may occur if the page containing the form is using an obsolete single-byte encoding like Windows-1252. Such automatic escaping is the only...
