At a glance

CVE-2022-33987 is a medium-severity URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the Simple Podcasting WordPress plugin, affecting versions <= 1.2.4. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.3.0; sites on affected versions should update now. Disclosed June 2022.

Vulnerability Overview

The got (JS Package) is vulnerable to Open Redirect in versions up to, and including, 11.8.4 as well as from 12 to below 12.1.0. Requested URLs are not verified and allow open redirection to a local UNIX socket.

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-601: URL Redirection to Untrusted Site ('Open Redirect')

Reaching this weakness in Simple Podcasting <= 1.2.4 takes a caller who can reach the endpoint. An open redirect is a page that takes a destination from the request and sends the browser there without checking that the destination belongs to the site.

A link that starts on a trusted domain finishes on an attacker's, which is what makes phishing and consent-screen abuse credible to the person clicking it. For Simple Podcasting the fix is 1.3.0: builds <= 1.2.4 are affected, anything from 1.3.0 onward is not.

Remediation

Update to version 1.3.0, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to Simple Podcasting: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Simple Podcasting 1.3.0 closes this, and updating the plugin is the step that ends it.
