At a glance

CVE-2021-25087 is a high-severity Improper Access Control vulnerability in the Download Manager WordPress plugin, affecting versions < 3.2.35. It carries a CVSS score of 7.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires no authentication. The issue is fixed in version 3.2.35; sites on affected versions should update now. Disclosed February 2022, reported by Diogo Real.

Vulnerability Overview

The Download Manager WordPress plugin before 3.2.35 does not have any authorisation checks in some of the REST API endpoints, allowing unauthenticated attackers to call them, which could lead to sensitive information disclosure, such as posts passwords (fixed in 3.2.24) and files Master Keys (fixed in 3.2.25).

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-284: Improper Access Control

Reaching this weakness in Download Manager < 3.2.35 takes a caller who can reach the endpoint. Improper access control means the code decides what a caller may do using something other than their actual permissions, so the decision can be wrong without any check appearing to be missing.

Whoever can shape the request decides the answer, so the protected action runs for callers the code never meant to allow. For Download Manager the fix is 3.2.35: builds < 3.2.35 are affected, anything from 3.2.35 onward is not.

Remediation

Update to version 3.2.35, 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: Download Manager 3.2.35 closes this, and updating the plugin is the step that ends it.
