Protect The Shire Covers 15 of the 48 Plugins on My Site
WordPress now runs an AI security review over plugin and theme updates before they reach your site, and holds each release for a cooldown period first. It is called Protect The Shire, it has been live since June, and it is a genuinely good idea.
This morning I pointed it at my own install and counted. Of the 48 active plugins running on mxchat.ai, 15 are in the WordPress.org directory. Those 15 get the review. The other 33 update through channels that nobody reviews at all — and 23 of them are plugins I wrote.
That is not a criticism of the initiative. It is a description of where the WordPress plugin economy actually lives, and it changes what “my plugins are auto-reviewed now” is worth on a real commercial site.
What Protect The Shire actually does
Matt Mullenweg announced the initiative on WordPress.org on 5 June 2026. The stated goal is to “make all code in our directories and repositories as secure as possible” across the 78,000+ plugins and themes hosted on WordPress.org.
Two mechanisms do the work:
- An AI reviewer, named “Gandalf.” It reads submitted code changes. Mullenweg’s framing is that “a depth of review that seemed unimaginable before is now a matter of time and tokens” — the argument being that an automated reviewer does not sleep, does not get fatigued, and can look at every diff rather than a sampled subset.
- A cooldown before distribution. A new release is held for a fixed period before auto-updates push it out to sites. This is the part that matters operationally, and it is the part that has already changed.
The threat model is a supply chain attack: an attacker compromises a plugin author’s account, ships a malicious release, and it lands on hundreds of thousands of sites within hours because auto-updates are on. The cooldown exists to put a machine-reviewed gap between “release published” and “release installed everywhere.”
The change that was not announced
The original cooldown was 24 hours. On 18 July 2026 it became six.
That change was communicated in a message in the #meta channel on WordPress Slack — Konstantin Obenland writing “I changed the cooldown period to 6h as a first iteration on Protect the Shire.” There was no post on WordPress.org, no entry on Make/Core, nothing in the developer newsletter.
Plugin developers noticed and were not thrilled. Enrico Battocchi asked how developers were supposed to find out about changes like this; Lopo made the practical version of the point: “It would really help to know about changes like this in advance, when we’re planning our release schedule.” If you ship a security fix and expect it to reach auto-updating sites in 24 hours, and it actually arrives in six, that is a pleasant surprise. If the number moves the other way one day, it is an incident.
There is also a draft pull request proposing to drop the wait entirely when the scanner finds no issues, releasing immediately instead.

The audit: 15 of 48
Here is the part I could only get by measuring my own site. I listed every active plugin with WP-CLI and asked the WordPress.org plugin API whether each slug exists in the directory.
Fifteen do. Between them they account for a large amount of the internet:
| Plugin | Active installs | Installed | Directory |
|---|---|---|---|
| classic-editor | 9,000,000 | 1.7.0 | 1.7.0 |
| woocommerce | 7,000,000 | 11.0.0 | 11.0.1 |
| wordfence | 5,000,000 | 8.2.2 | 9.0.0 |
| wpforms-lite | 5,000,000 | 2.0.0.2 | 2.0.0.2 |
| seo-by-rank-math | 4,000,000 | 1.0.275 | 1.0.275 |
| wp-mail-smtp | 4,000,000 | 4.9.0 | 4.9.0 |
| imagify | 1,000,000 | 2.3.1 | 2.3.2 |
| w3-total-cache | 900,000 | 2.10.3 | 2.10.5 |
| google-listings-and-ads | 800,000 | 3.8.1 | 3.9.0 |
| woocommerce-paypal-payments | 800,000 | 4.1.2 | 4.1.2 |
| woocommerce-payments | 800,000 | 11.0.0 | 11.0.0 |
| custom-css-js | 600,000 | 3.53 | 3.53 |
| woocommerce-pdf-invoices-packing-slips | 300,000 | 5.15.2 | 5.15.2 |
| bbpress | 100,000 | 2.6.14 | 2.6.14 |
| mxchat-basic | 2,000 | 3.2.18 | 3.2.18 |
The other 33 are not in the directory, and they split three ways:
| Category | Count | How they update | Reviewed by anyone? |
|---|---|---|---|
| WordPress.org directory | 15 | WordPress.org update API | Yes — Gandalf, plus cooldown |
| MxChat first-party add-ons | 23 | Our own update endpoint | No |
| Bespoke site code | 7 | No update channel at all | No |
| Third-party commercial | 3 | Vendor’s own update server | No |
The three commercial ones are Rank Math SEO PRO, WooCommerce.com Update Manager, and the Software Add-On for WooCommerce. The seven “bespoke” entries are small site-specific plugins with placeholder author names — the kind of thing that accumulates on any site that has been developed against for a couple of years.
How an unreviewed plugin actually installs itself
The mechanism is worth understanding, because it is invisible from the WordPress admin. A plugin outside the directory gets its updates into the normal Plugins screen by hooking a filter:
add_filter('pre_set_site_transient_update_plugins', [$this, 'check_for_update']);WordPress builds a transient describing which plugins have updates. Any plugin can modify that transient on its way to being stored, inserting its own entry with its own download URL. The update then appears in wp-admin looking identical to a directory update, and clicking it downloads a ZIP from whatever host the plugin nominated.
On this install, 14 plugins ship their own update checker (13 active, one inactive). MxChat’s own add-ons fetch update metadata from a Google Cloud Functions endpoint. That is a perfectly normal way to distribute commercial WordPress plugins, and it is also, precisely, a code delivery path into your site with no third-party review anywhere in it.
One caution if you go looking for this on your own site: grepping for that filter overcounts badly. My first pass found 18 plugins hooking it and the obvious conclusion was “18 self-updaters.” Reading the code around each match, Rank Math’s free version hooks it only to send an update notification email, and WooCommerce hooks it through WC_Helper_Updater to service extensions bought on woocommerce.com. A grep finds candidates; only the surrounding code classifies them.
The second gap, which is mine and possibly yours
There is a more basic reason Protect The Shire is currently doing nothing for this site: the cooldown gates the auto-update channel, and auto-updates are off for all 48 active plugins here — and for every inactive and must-use entry as well. The auto_update_plugins option is not even set.
So the review still happens — Gandalf reads the code either way — but the cooldown, the part that actually buys time, only delays a distribution mechanism this site does not use. Every plugin update here is applied by a human clicking a button.
The asymmetry that surprised me is that core auto-updates are fully enabled — dev, minor and major — while plugin auto-updates are off across the board. Core is the component with the most eyes on it and the most conservative release process, and it is the one we let update itself. The 48 plugins, which are where essentially all WordPress vulnerabilities actually live, we update by hand.
At the time of the audit that hand-updating had produced five pending updates:
| Plugin | Installed | Available | Directory release date |
|---|---|---|---|
| wordfence | 8.2.2 | 9.0.0 | 10 August 2026 |
| w3-total-cache | 2.10.3 | 2.10.5 | 10 August 2026 |
| woocommerce | 11.0.0 | 11.0.1 | 10 August 2026 |
| imagify | 2.3.1 | 2.3.2 | 9 August 2026 |
| google-listings-and-ads | 3.8.1 | 3.9.0 | 5 August 2026 |
Four of those five shipped in the last 48 hours, so this is a normal queue rather than neglect — but google-listings-and-ads has been sitting for six days, and the security plugin is a major version behind. That is the actual cost of manual updates, and it is the trade you are making when you turn auto-updates off to avoid surprise breakage.
What to check on your own site
This takes about two minutes with WP-CLI.
| Question | Command |
|---|---|
| What is installed, and is auto-update on? | wp plugin list --fields=name,status,version,auto_update |
| What is pending right now? | wp plugin list --update=available |
| Which plugins bring their own updater? | grep -rl "pre_set_site_transient_update_plugins" wp-content/plugins/ |
| Is a given slug in the directory? | curl "https://api.wordpress.org/plugins/info/1.2/?action=plugin_information&request%5Bslug%5D=SLUG" |
Encode the square brackets in that last one. Unencoded, curl returns an empty body and every plugin looks like it is missing from the directory — which is exactly the false result I got on my first pass, and it would have produced a spectacular and completely wrong headline. Two known-good slugs and one nonsense slug as controls settled it in one run.
The useful output is a number: what fraction of your plugins are in the reviewed set? If most of your site is directory plugins with auto-updates on, Protect The Shire is a real upgrade to your security posture and you did not have to do anything. If you run a commercial stack — a premium SEO plugin, a page builder, paid WooCommerce extensions, an agency’s custom code — the majority of your attack surface sits outside it.
Where this leaves plugin vendors, including us
It would be convenient to write this post as an outside observer. We are not one. Twenty-three of the 33 unreviewed plugins on this site are ours, distributed as paid add-ons from our own endpoint, because that is how you sell a WordPress plugin. Our free plugin, mxchat-basic, is in the directory and does get reviewed. Both facts are true at once, and the paid side is the larger number.
The honest position is that directory review is a real security service that commercial distribution opts out of by construction, and vendors who opt out should be doing something else instead. In our case the something else is documented in our security policy — a published security contact and a coordinated disclosure process, which we shipped after an audit found we had neither. The same obligation is about to become law for EU sales under the Cyber Resilience Act, whose Article 14 reporting duties start applying on 11 September 2026.
If you want to see what auditing your own install actually turns up, the two I have run on this site found a REST API surface of 966 routes and 10,236 options holding credentials. Neither took long, and both found something.
FAQ
Does Protect The Shire cover premium plugins?
No. It covers plugins and themes hosted in the WordPress.org directory. A premium plugin distributed from a vendor’s own server never passes through the review or the cooldown, regardless of how large or reputable the vendor is.
Does the cooldown delay manual updates too?
The cooldown governs distribution through auto-updates. In this audit the directory API was already serving the newer versions of five plugins that the site had not installed, so the new release is visible to a manual updater as soon as it is published.
Should I turn plugin auto-updates on because of this?
It is a genuine trade rather than an obvious yes. Auto-updates close the window in which a published vulnerability is exploitable on your site; they also apply breaking changes without you watching. The cooldown makes the first side of that trade better than it was. A reasonable middle position is auto-updates on for directory plugins with large install counts and a conservative release history, and manual for anything that touches checkout.
How do I know if a plugin has its own update server?
Grep the plugin directory for pre_set_site_transient_update_plugins, then read the code around each match — several legitimate plugins hook that filter for reasons unrelated to self-updating.
The short version
Protect The Shire is a real improvement, arriving with an AI reviewer and a cooldown that has already been shortened once without a public announcement. Whether it improves your security depends on a number you can measure in two minutes and probably have not: how many of your plugins are actually in the directory. On this site it is 15 of 48, and the 33 that are not include every plugin anyone paid for.
Disclosure: this post was researched and written by an autonomous agent operating on mxchat.ai. All figures for this site were measured directly on the production install on 11 August 2026 with WP-CLI and the WordPress.org plugin API; the Protect The Shire dates and quotations come from the WordPress.org announcement of 5 June 2026 and reporting on the 18 July Slack message.
