UpdraftPlus Changelog

The <a href="https://updraftplus.com/news/">UpdraftPlus backup blog</a> is the best place to learn in more detail about any important changes.

N.B. Paid versions of UpdraftPlus Backup / Restore have a version number which is 1 higher in the first digit, and has an extra component on the end, but the changelog below still applies. i.e. changes listed for 1.16.32.x of the free version correspond to changes made in 2.16.32.x of the paid version.

1.24.11 - 15/Nov/2024

TWEAK: Do not request drive.readonly scope on Google Drive connections, due to Google's app permissions review (unannounced and requires us to create a Youtube video for their review process) - this means that (until the review completes) new connections to Google Drive can only access backups created by UpdraftPlus directly, and not backups which you manually upload to Google Drive. This restores the ability to make new connections to Google Drive.
TWEAK: Adjustment of the UpdraftPlus_S3_Compat class to preserve compatibility with the external UpdraftPlus AWS SDK plugin (https://github.com/DavidAnderson684/updraftplus-aws-sdk).

1.24.9 - 14/Nov/2024

1.24.7 - 04/Nov/2024

TWEAK: Include the .part file extension into the cleanup list, guaranteeing that files associated with this extension are regularly deleted from the backup directory
TWEAK: The update functionalities in the WordPress plugin information box (6.5 and later) have been adjusted to stop updates from taking place in the same window, ensuring that the "auto-backup before update" dialog appears as intended
TWEAK: Add customized "unserialized" method into the UpdraftPlus class which can handle the use of the "options" argument or its absence when running across different PHP versions
TWEAK: Add the UPDRAFTPLUS_SEND_UNWRITABLE_BACKUP_DIRECTORY_EMAIL constant to disable the sending of unwritable backup directory emails to users.
TWEAK: Clearer notifications to users regarding unconfigured remote storage settings and/or the selection of remote storage that are not part of their UpdraftPlus version
TWEAK: During the resumption of OneDrive’s chunk uploads, the authorisation header and bearer token should not be included as it may lead to an unauthenticated error due to a different upload URL.

TWEAK: After a restoration, clicking "Delete old folders" will also remove the wp-config-pre-ud-restore-backup.php file
TWEAK: On the settings page/tab; prevent the floating "Save changes" button from getting clicked multiple times and/or sending multiple AJAX requests
TWEAK: Remove pCloud from the add-ons list on the "Premium / Extensions" tab (there is no change in its availability)
TWEAK: Renamed wp-config-backup.php to wp-config-pre-ud-restore-backup.php to clarify its purpose as a backup file created before restoring WordPress core entities, and it will only be generated if the user does not select the "Over-write wp-config.php" option during restoration, as the previous name was too generic and could cause confusion

1.23.11 - 03/Nov/2023

SECURITY: Fix a vulnerability which could, if you had Google Drive storage enabled, and if an attacker targetted a logged-in administrator on your site and persuaded them to access a specific URL that the attacker creates, add the attacker's own Google Drive account to the saved storage methods.

1.23.4 - 16/May/2023

SECURITY: Fixed a missing nonce combined with a URL sanitisation failure, which could lead to a targeted XSS opportunity (if an attacker persuades a logged-in administrator to both re-authorise their connection to a remote storage (e.g. Dropbox) and then to follow a link personally crafted for their site before re-authorising whilst logged in, he can then store a fixed JavaScript payload in the WP admin area (they would need a further route to use that ability to cause any damage). Because of the need for the administrator to co-operate in multiple steps, this attack is very unlikely (but you should of course still update).
FIX: DigitalOcean S3-compatible storage does not work with disabled SSL entirely where possible settings.
FIX: If there was an error or network connectivity issue on first attempt of uploading a plugin/theme file, then the second attempt of uploading the same file would make the file become corrupted thus resulting in installation failure.

SECURITY: This release fixes an important security defect - please update. Full details: https://updraftplus.com/updraftplus-1-23-3-2-23-3-important-security-release/. Sites are affected if there are WordPress users (i.e. people who can login) who can reach the back-end (i.e. wp-admin) dashboard (but we recommend everyone updates in any case).

FIX: A database backup couldn't be taken from WP-Optimize and All-In-One Security (AIOS) (regression)
TWEAK: Add a user capabilities check when downloading a backup (this is not believed to have any security implications, as the download operation already requires knowledge of a further nonce that there is no mechanism for a non-administrator to obtain).
TWEAK: Improve the Handlebars template of the UpdraftVault remote storage by taking PHP code out of it
TWEAK: Prevent making a nonce available to logged-in users who could not manage UpdraftPlus (this did not give access to any unauthorised actions)
TWEAK: Improve the Handlebars template of the UpdraftVault remote storage by taking PHP code out of it
TWEAK: Improve the Handlebars template of the pCloud remote storage by taking PHP code out of it

TWEAK: Use nonce when starting a new restoration and strengthen the continuation process to prevent direct access that has the potential of being file and/or log abuse
TWEAK: Improve the WebDAV storage module API in regard to the way it handles uploading and writing files
TWEAK: Replace the word "Directory" with "Folder" in UI notices
TWEAK: UpdraftVault: select storage class intelligently

SECURITY: Fixed a failure to sanitise printed URLs properly, leading to a targeted XSS opportunity (if an attacker persuades a logged-in admin to follow a link personally crafted for their site, he may be able to run JavaScript inside the browser - but on our testing, this ability is limited due to the sanitisation that was there - we have not been able to confirm that a payload causing damage is possible).

1.22.3 - 15/Feb/2022

SECURITY: Thanks to Marc-Alexandre Montpas of Automattic for this report (CVE: CVE-2022-23303). All versions of UpdraftPlus from March 2019 onwards have contained a vulnerability caused by a missing permissions-level check, allowing untrusted users access to backups. If your site does not have non-admin users, or if your non-admin users are all trusted (and your site does not allow users to sign up themselves), then you are not vulnerable (but we always recommend updating to the latest version in any case). Please see https://updraftplus.com/updraftplus-security-release-1-22-3-2-22-3/ for more details.
FIX: Unexpected 'Backup History' array structure during the rescanning of the new backup sets that changed the type of the database associative keys from string to array format

SECURITY: Fix a non-persistent XSS error allowing an attacker to once run JavaScript in your web browser if you clicked on a link crafted personally for you whilst logged into your site (very similar to that fixed in 1.16.65/6). A packaging error meant that this was not properly fixed in the 1.16.67-68 releases.

FIX: If MySQL performance was very fast on large tables, and if fallback fetch mode was being used (which should not occur on any WordPress core table, but can be triggered on recent Oracle MySQL 8.0 versions), then when increasing rows fetched on large tables, some rows could be unintentionally skipped.
TWEAK: Oracle MySQL 8.0 from somewhere after 8.0.17 has removed the display width from the response to SHOW CREATE TABLE, resulting in failure (prior to this tweak) to detect a primary key type that can be used with faster fetching
TWEAK: Use 'wp_mail_failed' action hook to improve logging of email delivery failures caused by a PHPMailer exception

TWEAK: Cycle Dropbox API client ID (old one has been cycled and no longer works)

1.16.37 - 23/Nov/2020

1.16.35 - 19/Nov/2020

FEATURE: Backup destinations with conditional logic rules for scheduled backups (Premium)
FIX: A regression in 1.16.30 meant that the term_relationships table could have rows missing in the backup if mysqldump was not present/used; this meant that items with multiple terms were only having one relationship backed up (e.g. multiple tags being assigned to one post)
TWEAK: Adding remote block assets support when editing post from UpdraftCentral
TWEAK: Rename UpdraftCentral's main and listener classes
TWEAK: Improve error message when encrypted key given by user for SFTP/SCP remote storage method

TWEAK: Replace uses of php_uname() function with PHP_OS constant when the server where PHP is running on disables the function for security reasons

TWEAK: Integrate UpdraftPlus and WordPress 5.5 core's automatic update settings
TWEAK: When a backup resumed, the last successful resumption was incorrectly set as the last successful resumption when an 'alive' event was recorded, rather than a 'useful' one; this deferred some mitigations when there was insufficient progress
TWEAK: Add another tweak to paid versions' update checking time algorithm
TWEAK: Add "Select all" and "Deselect all" link texts for bulk selecting/deselecting tables from the database table list on the manual backup dialog

TWEAK: Remove the now-redundant concept of inner loops from the database table backup routine

1.16.31 - 20/Oct/2020

FIX: A regression in 1.16.30 meant that tables with integer primary keys which used signed integers omitted the first row of the table from the backups. This is not common (e.g. it does not affect any core WP tables; most plugins adding tables follow WP core in using unsigned integers for primary keys).

1.16.30 - 15/Oct/2020

PERFORMANCE: Where a table has a numerical primary key, extract its data using that index. This results in a substantial performance increase when fetching large tables using PHP. (The filter updraftplus_can_use_primary_key_default can be used to de-activate this behaviour).
FIX: Remove incorrect decodeURIComponent() parsing when importing settings, which could prevent import of settings containing some special characters
FIX: An issue where database tables that were not selected to be backed up in a "Backup Now" backup would get added to the backup during a resumption (i.e. if it did not finish in a single run)

TWEAK: Show a notification of UpdraftPlus plugin updates even if the associated user account is not connected to the UpdraftPlus website
TWEAK: Add mechanism to detect what hosting provider is being used and use it to make UpdraftPlus comply with Kinsta's backup limit policies (thus removing it from the list of disallowed plugins)
TWEAK: When booting a clone if it's claimed from the clone queue then update the token being used
TWEAK: Tweaked downwards the minimum time in the future for rescheduling a resumption

1.16.29 - 08/Sep/2020

FIX: Added Africa (Cape Town), Asia Pacific (Hong Kong) & Asia Pacific (Osaka-Local) to AWS

NOTE: The free version 1.16.27 was released as 1.16.26; i.e. if confused about 1.16.26 went, then the answer is that they are the same thing.

1.16.25 - 23/May/2020

FIX: Dropbox since 1.16.24 was only deleting one backup files archive out of the set. i.e. Excess archives remained on Dropbox. These have to be deleted manually.
TWEAK: Add version to CSS and JS within filenames to prevent old versions being served after update on sites which have customisations to remove the query string

TWEAK: Update class-udrpc to latest (1.4.14) which removes a conflict with other code that may interact with CORS OPTIONS requests
TWEAK: Escape log lines when sending for display (theoretically an XSS security issue, but to achieve a successful attack, someone would have to first get something malicious into the log file, which is difficult as there are not many places where foreign input can end up in the log file - e.g. hack into Dropbox and cause Dropbox to send you back malicious HTML in an error message - and then be able to persuade you to both take a backup triggering the problem and then view the log file in your WP dashboard)
TWEAK: Update Google Cloud bucket locations

1.13.1 - 09/May/2017

REFACTOR: Completed re-factoring of the remote storage modules, so that now all remote storage code has completed this current stage of re-factoring (more to come in future - laying the foundation for a significant new feature)
FIX: Added a nonce to the Dropbox deauth link. This is a minor security issue - someone personally targeting you, who knew that you were logged in to your WordPress admin, and who could persuade you to visit a personally-crafted web page, could cause the connection between UpdraftPlus and your Dropbox to be broken. The only impact of this is that the sending of your next backup to Dropbox would fail, and you would be alerted about the need to re-connect.
FIX: Import settings now handle the new remote storage options format
FIX: The zip file browser was not working in free versions
TWEAK: Added a version check when saving settings to prevent errors or lost settings
TWEAK: 'Existing Backups' table now shows an icon for each remote destination that the backup was sent to

FIX: Fix an issue that could occasionally cause corruption of interrupted Dropbox backups. All Dropbox users are recommended to update asap.
TWEAK: Remove debugging statement inadvertently left in 1.12.36
TWEAK: Re-factored remote storage handlers via add-ons so that there was a cleaner and more consistent class hierarchy (preparation for future improvements). N.B. If you subsequently downgrade to an older version of UpdraftPlus, you will need to re-enter the settings for some remote storage options.
TWEAK: List of checksum algorithms run over backups and logged now includes SHA256, and is filterable (SHA1 now considered deprecated)
TWEAK: Allow chunked database encryption to try and resume in the event of an error
TWEAK: Improve the premium/extension tab content
TWEAK: Fix an issue whereby the UpdraftVault settings section could show a bogus problem with checking quota immediately after initial setup
