Vulnerability Overview

The sell-downloads plugin before 1.0.8 for WordPress has insufficient restrictions on brute-force guessing of purchase IDs.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality.

CWE-20: Improper Input Validation

Reaching this weakness in Sell Downloads < 1.0.8 takes a caller who can reach the endpoint. Improper input validation means the application accepts input without confirming it has the form, type or range the code downstream assumes.

The concrete impact depends on where the unvalidated value lands, which is why records in this class range from cosmetic bugs to full compromise. For Sell Downloads the fix is 1.0.8: builds < 1.0.8 are affected, anything from 1.0.8 onward is not.

Remediation

Update to version 1.0.8, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Sell Downloads: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Sell Downloads 1.0.8 closes this, and updating the plugin is the step that ends it.
