# Contest Gallery WordPress plugin: vote limit bypassed by spoofed visitor identity

The Contest Gallery WordPress plugin trusts a client-supplied request header and an unbound client-generated token to enforce its one-vote-per-entry rule. An unauthenticated visitor can send crafted requests to cast repeated votes for the same entry and inflate its total.

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

## How to check

- Look for the Contest Gallery plugin in the WordPress admin plugin list and read its installed version.
- Check whether any contest on the site uses public voting, since the bypass only affects vote counts.
- `wp plugin get contest-gallery --field=version` if WP-CLI is available.

## Fix

- Update the Contest Gallery plugin to `34.0.1` or later.
- Review vote totals on active contests for implausible spikes from a single source and reset them if needed.

## From the sources

The Contest Gallery WordPress plugin before 34.0.1 does not reliably validate the visitor identity used to enforce its one-vote-per-entry restriction, trusting a client-supplied request header and an unbound client-generated token, which allows unauthenticated users to bypass the restriction and cast multiple votes for the same contest entry, inflating its vote total.
