At a glance

This record tracks a critical-severity Improper Access Control vulnerability in the Realia WordPress plugin, affecting versions <= 1.4.0. It carries a CVSS score of 9.1 (reachable over the network; low attack complexity; high integrity, availability impact). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed October 2020, reported by Erwan LR.

Vulnerability Overview

The Realia plugin for WordPress is vulnerable to Arbitrary Post Deletion in versions up to, and including, 1.4.0. This is due to the 'includes/class-realia-submission.php' file. This makes it possible for unauthenticated attackers to delete any post within the vulnerability's scope.

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 integrity, availability.

CWE-284: Improper Access Control

Reaching this weakness in Realia <= 1.4.0 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. No fixed build of this plugin is recorded for Realia 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.

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. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
