CVE-2025-57994 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the Upcoming Events Lists WordPress plugin, affecting versions <= 1.4.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above.

Vulnerability Overview

The Upcoming Events Lists plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 1.4.0 due to missing validation on a user controlled key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to perform an unauthorized action.

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 interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Upcoming Events Lists <= 1.4.0 takes an account at Subscriber level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. No fixed build of this plugin is recorded for Upcoming Events Lists yet, so installs running <= 1.4.0 stay exposed until the vendor ships one.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
