What is CVE-2026-81021?

The SupportCandy plugin for WordPress prior to version 3.5.3 lacks sufficient authorization checks for its ticket attachment download functionality. This oversight permits unauthorized attackers to access and download sensitive customer-uploaded attachments by simply enumerating the sequential identifiers of these attachments, posing a risk to user privacy and data security.

Affected Version(s)

SupportCandy 3.2.9 < 3.5.3

Exploit Proof of Concept (PoC)
