WordPress 5.4.2 Security and Maintenance Release

Posted June 10, 2020 by Jake Spurlock. Filed under Releases, Security.

WordPress 5.4.2 is now available!

This security and maintenance release features 23 fixes and enhancements. Plus, it adds a number of security fixes—see the list below.

These bugs affect WordPress versions 5.4.1 and earlier; version 5.4.2 fixes them, so you’ll want to upgrade.

If you haven’t yet updated to 5.4, there are also updated versions of 5.3 and earlier that fix the bugs for you.

Security Updates

WordPress versions 5.4 and earlier are affected by the following bugs, which are fixed in version 5.4.2. If you haven’t yet updated to 5.4, there are also updated versions of 5.3 and earlier that fix the security issues.

  • Props to Sam Thomas (jazzy2fives) for finding an XSS issue where authenticated users with low privileges are able to add JavaScript to posts in the block editor.
  • Props to Luigi – (gubello.me) for discovering an XSS issue where authenticated users with upload permissions are able to add JavaScript to media files.
  • Props to Ben Bidner of the WordPress Security Team for finding an open redirect issue in wp_validate_redirect().
  • Props to Nrimo Ing Pandum for finding an authenticated XSS issue via theme uploads.
  • Props to Simon Scannell of RIPS Technologies for finding an issue where set-screen-option can be misused by plugins leading to privilege escalation.
  • Props to Carolina Nymark for discovering an issue where comments from password-protected posts and pages could be displayed under certain conditions.

Thank you to all of the reporters for privately disclosing the vulnerabilities. This gave the security team time to fix the vulnerabilities before WordPress sites could be attacked.

One maintenance update was also deployed to versions 5.1, 5.2 and 5.3. See the related developer note for more information.

You can browse the full list of changes on Trac.

For more info, browse the full list of changes on Trac or check out the Version 5.4.2 documentation page.

WordPress 5.4.2 is a short-cycle maintenance release. The next major release will be version 5.5.

You can download WordPress 5.4.2 from the button at the top of this page, or visit your Dashboard → Updates and click Update Now.

If you have sites that support automatic background updates, they’ve already started the update process.

Thanks and props!

Equity and the Power of Community

Posted June 6, 2020 by Josepha. Filed under Community, General.

Over the past week, I’ve been thinking a lot about George Floyd, Breonna Taylor, and Ahmaud Arbery. I have been thinking about white supremacy, the injustice that Black women and men are standing up against across the world, and all the injustices I can’t know, and don’t see. 

The WordPress mission is to democratize publishing, and to me, that has always meant more than the freedom to express yourself. Democratizing publishing means giving voices to the voiceless and amplifying those speaking out against injustice. It means learning things that we otherwise wouldn’t. To me, it means that every voice has the ability to be heard, regardless of race, wealth, power, and opportunity. WordPress is a portal to commerce; it is a canvas for identity, and a catalyst for change.

While WordPress as an open source project may not be capable of refactoring unjust judicial systems or overwriting structural inequality, this does not mean that we, the WordPress community, are powerless. WordPress can’t dismantle white supremacy, but the WordPress community can invest in underrepresented groups (whose experiences cannot be substituted for) and hire them equitably. WordPress can’t eradicate prejudice, but the WordPress community can hold space for marginalized voices in our community.

There is a lot of racial, societal, and systemic injustice to fight. At times, change may seem impossible, and certainly, it’s been too slow. But I know in my heart that the WordPress community is capable of changing the world. 

If you would like to learn more about how to make a difference in your own community, here are a few resources I’ve gathered from WordPressers just like you.

The Month in WordPress: May 2020

Posted June 2, 2020 by Angela Jin. Filed under Month in WordPress.

May was an action-packed month for WordPress! WordPress organizers are increasingly moving WordCamps online, and contributors are taking big steps towards Full Site Editing with Gutenberg. To learn more and get all the latest updates, read on. 


Gutenberg 8.1 and 8.2

Gutenberg 8.1 was released on May 13, followed quickly by Gutenberg 8.2 on May 27. 

  • 8.1 added new block pattern features making it easier to insert desired patterns, along with a new pattern. It also added a button to  collapsed block actions for copying the selected block, which will help touchscreen users or users who don’t use keyboard shortcuts. 
  • 8.2 introduced block pattern categories and a `viewportWidth` property that will be particularly useful for large block patterns. There is also a new content alignment feature, and enhancements to improve the writing experience. 

Both releases include a number of new APIs, enhancements, bug fixes, experiments, new documentation, improvement to code quality, and more! To learn the latest, visit the announcement posts for Gutenberg 8.1 and Gutenberg 8.2.

Gutenberg Phase 2: Steps Towards Full Site Editing

Contributors are currently working hard on Phase 2 of Gutenberg! Where Phase 1 introduced the new block editor with WordPress 5.0, Phase 2 sees more customization and includes one of the biggest Gutenberg projects: Full Site Editing (FSE). At the moment, work on WordPress 5.5 has been initiated and contributors decided to include basic functionality for Full Site Editing in this release. FSE hopes to streamline the site creation and building process in WordPress using a block-based approach. There’s a lot of conversation and new information about FSE, so communication around the project is very important. On May 28th, a conversation was held in the #core-customize channel to discuss FSE and the future of the Customizer. To help everyone track the latest information, this post summarizes ways to keep up with FSE.

Theme Review Team Rebranding

Representatives of the Themes Review Team have decided to update their team name to “Themes Team.” This decision reflects changes that the block editor brings to the landscape of themes with the Full Site Editing project. The team has always been involved in projects beyond reviewing wporg.ibadboy.net themes and lately, the team has been contributing more to themes in general — including open-source packages, contributions to Full Site Editing, the Twenty Twenty theme, and more. You can read more about the name change in the team’s meeting notes.

Online WordCamp Program Announced

To assist organizers with moving their WordCamps online, the WordPress Community team has prepared a new set of guidelines for online WordCamps. The Community Team will cover online production and captioning costs associated with any online WordCamp without the need for local sponsorship. The team also updated its guidelines to cover the regional focus of online events, and modified the code of conduct to cater to the new format. The WordCamp schedule has also been updated to indicate whether an event is taking place online or not. You can find resources, tools, and information about online WordPress events in our Online Events Handbook. They have also prepared a new set of guidelines for in-person events taking place in 2020, in the light of COVID-19 challenges. 

Want to get involved with the Community team? Follow the Community blog here, or join them in the #community-events channel in the Making WordPress Slack group. To organize a Meetup or WordCamp, visit the handbook page

BuddyPress 6.0.0 “iovine’s”

On May 13th, BuddyPress 6.0.0, known as “iovine’s,” was released. This release includes two new blocks for the WordPress Editor: Members and Groups. It also saw the completion of the BP REST API, adding the six remaining endpoints, and the move or local avatar management to the Members component. Beyond that, 6.0.0 includes more than 80 changes, made possible by 42 contributors. 

Want to download this latest version of BuddyPress? Get it here.  You can also help by translating BuddyPress into another language or letting the team know of any issues you find in the support forums.

WordCamp Spain Online Concludes Successfully

WordPress Meetup organizers in Spain joined hands to organize WordCamp Spain online from May 6 to 9, which proved to be a huge success. The event had more than 5,500 attendees, 60 speakers, and 16 sponsors. Over 200 people from around the world participated in the Contributor Day. Matt Mullenweg hosted an AMA for the participants, facilitated by Mattias Ventura’s on-the-spot Spanish translation. 

If you missed the event, you can watch videos from WordCamp Spain online at WordPress.TV. Want to organize a regional WordCamp? Learn more about that here!
