At a glance

CVE-2026-118041 is a high-severity Unrestricted Upload of File with Dangerous Type vulnerability in the Contest Gallery WordPress plugin, affecting versions < 34.0.3. It carries a CVSS score of 8.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires an authenticated account at Author level or above. The issue is fixed in version 34.0.3; sites on affected versions should update now. Disclosed November 2026, reported by Izzny.

Vulnerability Overview

The Contest Gallery – Upload & Vote Photos, Media, Sell with PayPal & Stripe plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to 34.0.3. This is due to missing file type validation. This makes it possible for authenticated attackers, with author-level access and above, to upload arbitrary files on the affected site's server, which may make remote code execution possible.

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, integrity, availability — full site compromise territory.

CWE-434: Unrestricted Upload of File with Dangerous Type

Reaching this weakness in Contest Gallery < 34.0.3 takes an account at Author level or above. An unrestricted file upload lets a caller store a file whose type or destination the application does not properly constrain.

If an uploaded file lands anywhere the server will execute, the flaw becomes remote code execution and the site should be treated as fully compromised. For Contest Gallery the fix is 34.0.3: builds < 34.0.3 are affected, anything from 34.0.3 onward is not.

Remediation

Update to version 34.0.3, or a newer patched version

How does WordSec protect against this?

An attacker needs Author 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. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Contest Gallery 34.0.3 closes this, and updating the plugin is the step that ends it.
