1.  From the dashboard of your site, navigate to Plugins –> Add New.
2.  Select the Upload option and hit “Choose File.”
3.  When the popup appears select the event-tickets.x.x.zip file from your desktop. (The ‘x.x’ will change depending on the current version number).
4.  Follow the on-screen instructions and wait as the upload completes.
5.  When it’s finished, activate the plugin via the prompt. A message will show confirming activation was successful.
6.  For access to new updates, make sure you have added your valid License Key under Tickets –> Settings –> Licenses.

**Are there any troubleshooting steps I should try before I post a new thread in the support forum?**

First, make sure that you’re running the latest version of Event Tickets. If you’ve got any other add-ons, make sure those are current and running the latest code as well. Also be sure to check our knowledgebase.

The most common issues we see are either plugin or theme conflicts. You can test if a plugin or theme is conflicting by manually deactivating other plugins until just Event Tickets is running on your site. If the issue persists, revert to the default Twenty Twenty theme. If the issue is resolved after deactivating a specific plugin or your theme, you’ll know that is the source of the conflict.

Note that we aren’t going to say “tough luck” if you identify a plugin/theme conflict. While we can’t guarantee 100% integration with any plugin or theme out there, we will do our best (and reach out the plugin/theme author as needed) to figure out a solution that benefits everyone.

**I’m still stuck. Where do I go to file a bug or ask a question?**

Free plugin users can post in the Event Tickets support forum on WordPress.org. Our team reviews that forum weekly to look for bug reports.

If you’re already an Event Tickets Plus subscriber, you’re entitled to our actively-monitored Premium Support on our website. Generally, except in times of increased support loads, we reply to all premium support tickets within 24 hours during the business week.

**What’s the difference between Event Tickets and Events Tickets Plus?**

Event Tickets is our free ticketing plugin that has all the basics you need to sell tickets and collect RSVPs on your website. You can use Event Tickets with or without The Events Calendar.

Event Tickets Plus is a premium plugin that runs alongside Event Tickets and enhances it with extra features, including custom registration fields, shortcodes, WooCommerce integration, enhanced Stripe functionality for Stripe for Tickets Commerce, our mobile ticketing app and more.

**Do I need The Events Calendar to run Event Tickets?**

Nope! Event Tickets works with or without The Events Calendar. Even if you don’t have The Events Calendar, you can create RSVPs and tickets on WordPress pages and posts.

**Can I email attendees using Event Tickets?**

Yes. Event Tickets automatically sends an email confirmation after attendees register or RSVP for an event. If the attendee purchases a ticket, the confirmation email will also provide a ticket to scan at the door for admission.

**I’ve still got questions. Where can I find answers?**

Check out our extensive knowledgebase for articles on using, tweaking, and troubleshooting our plugins.

Both my client and myself are very disappointed with the modernization process of TEC + Tickets Pro to the Block Editor. Every step has been painful for over 6 months. We’ll be replacing this with a competing plugin.

Email support was good. Apart from referring to the manuals, as they should, they still investigated further and gave us a solution for our problem. Well done!

So many bug when it comes to payment and support is so so so slow. I am losing sales because to this. Using Stripe: Apple pay freezes No Way to turn off Apple Pay, turning it off doesnt save Can't validate webhook Support keeps asking me to create a staging to test, sure, but they take a week to reply. Some support staff even told me they have no experience with apple pay and it is not their feature, i mean...come on...its right there in your setting

Followed the documentation, but cannot get Stripe to validate webhook. Read other support threads and have confirmed that everything is in order as per the documentation. I was testing out the plugin, but given the time wasted, there is no way I will continue to use it to sell tickets if the free version which includes a 2% fee doesn't work, why would I bother upgrading to the premium version. Seem to much of a risk. Also, looking at people comments, it seems support is slow (they are constantly away from the office/out of the office. Look at other plugins out there.

Constant issues. Nearly impossible to make work. Stops working for no apparent reason. I make websites, used probably hundreds of different plugins over the years. This is in the top 5 worst. There is an easy/user friendly way to do things. This plugin does the opposite in nearly every avenue.

Despite having over 18 months of warning from EDD that their plugin needed updating, they have failed to make any progress whatsoever. They use incompatible, depreciated methods which means tickets sold do not have the attendees details saved, just the purchaser. If I could give this negative stars, I would.

CVE-2019-5070: TALOS-2019-0859 || Cisco Talos Intelligence Group

The rsvpmaker plugin before 6.2 for WordPress has SQL injection.

CVE-2019-15646: RSVPMaker

The ad-inserter plugin before 2.4.20 for WordPress has path traversal.

CVE-2019-15323: Ad Inserter – Ad Manager & AdSense Ads

The give plugin before 2.4.7 for WordPress has XSS via a donor name.

**Exploitation Level:** Medium / Remote

**DREAD Score:** 6.6

**Vulnerability:** Stored XSS on an administrative page

**Patched Version:** 2.4.7

​​Give is a WordPress plugin which allows users to setup a donation page on a website. It currently has 60k installs.

​​During a recent audit of the plugin, we found a severe vulnerability which allows donors to inject arbitrary code on an administrative page.

​​If you are using a version lower than **2.4.7,** you should update immediately.

> Note: A forced update was pushed by the developers, and all affected users should now be patched and protected against this vulnerability.

​​When creating a donation, all of the arguments are sanitized as text fields, but this method does not take into consideration where the variables are reflected. Thanks to this oversight, a malicious user can still perform an injection on the donors page after making a donation.

​​Due to the reflection point, the injection can only be seen by users with sufficient permissions to see the donors — this means that a malicious script could do a lot of damage while acting as these users.

****​​Technical Details****

​​When processing a donation, the plugin recursively sanitizes every POSTed variable using the sanitize\_text\_field method.

​​The function handling the donation form

​​The function recursively cleaning text fields

​​Under this plugin, a **Donation** uses multiple data structures:

*   ​​**Donation**, which contains the donation content itself.

*   **Donor**, which contains the data related to the user performing the donation.

​​​​If the user performing the donation is a guest, meaning this is the first donation using this email, a new donor will be created with the provided information.

​​Donor creation

​​Under the admin panel, you can see either one of the two created entities by the donation: The **Donors** and The **Donations**.

​​Both of these pages are tables where we can see, filter, and modify the data. On the Donors table, few custom attributes are added on tags to facilitate the website interactivity. Among these is the _data-name_ attribute, which has the donor name value. As you can see on the donor creation code, this value is the full name of the donor. This attribute is used on two tags: The row tag and the column checkbox input.

​​The code can be found under _class-donor-table.php:_

​​Injection on the table row tag

​​Injection on the column checkbox

​​The name of our user was sanitized using the _sanitize\_text\_field_ method, which performs the following actions per the WordPress documentation:

*   ​​Checks for invalid UTF-8

*   ​​Converts single < characters to entities

*   ​​Strips all tags

*   ​​Removes line breaks, tabs, and extra whitespace

*   ​​Strips octets

​​You might notice it removes the **_tags_**, but it does not mention being safe as **_attribute._** ​​With that in mind, it is possible to escape the _data-name_ attribute and add an event on the input.

​Having the following name:

_Name " onfocus="alert(document.domain)" autofocus="_

gives us the following HTML on the input injection:

_<input class="donor-selector" type="checkbox" name="donor\[\]" value="1"_ 

  _data-name="Name_ **_"_** 

  **_onfocus="alert(document.domain)"_** 

  **_autofocus=""_** _/>_

Using the autofocus attributes will trigger the onfocus event without user interaction, which can execute malicious code.

**Conclusion**

Cross-site scripting (XSS) is a widespread vulnerability that allows an attacker to inject malicious content into a site.

In the case of Stored XSS (as seen with this particular vulnerability), the payload is stored in the site’s database and retrieved with every page request. If left unpatched, it can be very dangerous, as an attacker acting as a donor can obtain complete control of the browser environment.

To protect against this vulnerability, we strongly encourage **Give** users to update to **version 2.4.7** as soon as possible. In the event that you can’t immediately update your plugin, you can leverage the Sucuri Firewall or equivalent technology to virtually patch the vulnerability.
