At a glance

CVE-2026-84898 is a medium-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Eventin WordPress plugin, affecting versions < 4.1.21. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity; high confidentiality impact). Exploitation requires an authenticated account at Contributor level or above. The issue is fixed in version 4.1.21; sites on affected versions should update now. Disclosed September 2026, reported by Sai Praneeth Koti.

Vulnerability Overview

The Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce plugin for WordPress is vulnerable to Path Traversal in all versions up to 4.1.21. This is due to insufficient validation of a user supplied path. This makes it possible for authenticated attackers, with contributor-level access and above, to access files and directories outside of the intended directory.

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. A successful exploit has high impact on confidentiality.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in Eventin < 4.1.21 takes an account at Contributor level or above. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Eventin the fix is 4.1.21: builds < 4.1.21 are affected, anything from 4.1.21 onward is not.

Remediation

Update to version 4.1.21, or a newer patched version

How does WordSec protect against this?

An attacker needs Contributor access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Eventin 4.1.21 closes this, and updating the plugin is the step that ends it.
