At a glance

CVE-2024-31275 is a medium-severity External Control of Assumed-Immutable Web Parameter vulnerability in the EventPrime WordPress plugin, affecting versions <= 3.3.4. 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 3.3.5; sites on affected versions should update now. Disclosed April 2024, reported by Joshua Chan.

Vulnerability Overview

The EventPrime plugin for WordPress is vulnerable to booking price manipulations due to insufficient validation and control of booking prices in versions up to, and including, 3.3.4. This makes it possible for unauthenticated attackers to make bookings with lower prices.

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-472: External Control of Assumed-Immutable Web Parameter

Reaching this weakness in EventPrime <= 3.3.4 takes a caller who can reach the endpoint. External control of an assumed-immutable parameter means the code trusts a value it believes cannot be changed by the caller, when in fact the request carries it.

Editing that field changes the outcome of the operation, which on commerce plugins means altered prices or totals and on account flows means acting as another user. For EventPrime the fix is 3.3.5: builds <= 3.3.4 are affected, anything from 3.3.5 onward is not.

Remediation

Update to version 3.3.5, or a newer patched version

How does WordSec protect against this?

The attempt arrives as an ordinary request to EventPrime: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: EventPrime 3.3.5 closes this, and updating the plugin is the step that ends it.
