Vulnerability Overview

The WP Photo Album Plus plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 8.5.02.005 due to missing validation on a user controlled key. This makes it possible for unauthenticated attacker to perform an unauthorized action base don a user controlled key.

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.

CWE-639: Authorization Bypass Through User-Controlled Key

Reaching this weakness in WP Photo Album Plus <= 8.5.02.005 takes a caller who can reach the endpoint. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For WP Photo Album Plus the fix is 8.6.01.005: builds <= 8.5.02.005 are affected, anything from 8.6.01.005 onward is not.

Remediation

Update to version 8.6.01.005, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: WP Photo Album Plus 8.6.01.005 closes this, and updating the plugin is the step that ends it.
