Stored XSS in Tickera WordPress Plugin via price_wrapper Shortcode

Publication date: 2026-07-16

Last updated on: 2026-07-16

Assigner: Wordfence

Description
The Tickera – Sell Tickets & Manage Events plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'price_wrapper' Shortcode Attribute in all versions up to, and including, 3.6.0.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful execution of the injected script is limited to victims who have the referenced ticket ID present in their cart cookie, meaning the payload only fires for users who have previously added that ticket to their cart.

Executive Summary

The Tickera WordPress plugin up to version 3.6.0.0 has a stored cross-site scripting (XSS) vulnerability in the 'price_wrapper' shortcode attribute. This flaw allows authenticated attackers with contributor-level access or higher to inject malicious scripts into pages. The scripts execute only for users who have added a specific ticket to their cart.

Impact Analysis

If you use the Tickera plugin, attackers could inject scripts that run when users visit pages with affected tickets in their cart. This could lead to theft of session cookies, account takeover, or defacement of your WordPress site.

Compliance Impact

This vulnerability could compromise user data privacy, potentially violating GDPR (data protection) or HIPAA (health information security) if exploited. Unauthorized script execution may lead to unauthorized access to personal data.

Mitigation Strategies

Update the Tickera plugin to the latest version beyond 3.6.0.0 to patch the vulnerability. If updating is not possible, consider disabling the plugin temporarily until a patch is applied.
