Vulnerability in SupportCandy – AI Customer Support Ticket System & Live Chatbot Agent — CVE-2026-94378

What to do now

Update SupportCandy – AI Customer Support Ticket System & Live Chatbot Agent to 3.5.4 or later.

Affected versions

• Everything up to and including 3.5.3

The SupportCandy – AI Customer Support Ticket System & Live Chatbot Agent plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'name' parameter in all versions up to, and including, 3.5.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This exploit chain requires the 'Register user if not exists' setting to be disabled, which is its default configuration.
