# WordPress Contest Gallery plugin: uploads let Author users run code on server

Link for people: https://infrastack.ai/live/CVE-2026-118041 (this .md is for agents)

The Contest Gallery WordPress plugin before 34.0.3 does not sanitise file names uploaded through its e-commerce sale file-replacement feature. An authenticated user with Author-level access or higher can write files with arbitrary names and extensions into a web-accessible directory, and can overwrite the directory's protection file to achieve remote code execution.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Contest Gallery plugin version in the WordPress admin Plugins page; unknown whether a specific file path or setting exposes it.

## Fix

- Contest Gallery: move to `34.0.3` or later (the fixed version named in the description).

## Timeline

- 2026-11-11T06:25:41+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-118041

## From the sources

The Contest Gallery  WordPress plugin before 34.0.3 does not sanitise the name of files uploaded through its e-commerce sale file-replacement feature, allowing authenticated users with Author-level access and above to write files with an arbitrary name and extension to a web-accessible directory and, by overwriting the directory's protection file through the same flow, achieve Remote Code Execution.
