CKEditor 4.19.0

New features:

#2444: Togglable toolbar buttons are now exposed as toggle buttons in the browser’s accessibility tree.
#4641: Added an option allowing to cancel the Delayed Editor Creation feature as a function handle for editor creators (CKEDITOR.replace, CKEDITOR.inline, CKEDITOR.appendTo).
#4986: Added config.shiftLineBreaks allowing to preserve inline elements formatting when the shift+enter keystroke is used.
#2445: Added config.applicationTitle configuration option allowing to customize or disable the editor’s application region label. This option, combined with config.title, gives much better control over the editor’s labels read by screen readers.

Fixed Issues:

#4543: Fixed: Toolbar buttons toggle state is not correctly announced by screen readers lacking the information whether the feature is on or off.
#4052: Fixed: Editor labels are read incorrectly by screen readers due to invalid editor control type for the Iframe Editing Area editors.

#4855: [iOS] Fixed: Focusing toolbar buttons with an enabled VoiceOver screen reader moves the browser focus into an editable area and interrupts button functionality.

API changes:

#4641: The CKEDITOR.replace, CKEDITOR.inline, CKEDITOR.appendTo functions are now returning a handle function allowing to cancel the Delayed Editor Creation feature.
#5095: Added the CKEDITOR.plugins.clipboard.addFileMatcher function allowing to define file formats supported by the clipboard plugin. Trying to paste unsupported files will result in a notification that a file cannot be dropped or pasted into the editor.
#2445: Added config.applicationTitle alongside CKEDITOR.editor#applicationTitle to allow customizing editor’s application region label.

CKEditor 4.18.0

Security Updates:

Fixed an XSS vulnerability in the core module reported by GitHub Security Lab team member Kevin Backhouse.

Issue summary: The vulnerability allowed to inject malformed HTML bypassing content sanitization, which could result in executing a JavaScript code. See CVE-2022-24728 for more details.

Fixed a Regular expression Denial of Service (ReDoS) vulnerability in dialog plugin discovered by the CKEditor 4 team during our regular security audit.

Issue summary: The vulnerability allowed to abuse a dialog input validator regular expression, which could cause a significant performance drop resulting in a browser tab freeze. See CVE-2022-24729 for more details.

An upgrade is highly recommended!

Highlights:

Web Spell Checker ended support for WebSpellChecker Dialog on December 31st, 2021. This means the plugin is not supported any longer. Therefore, we decided to deprecate and remove the WebSpellChecker Dialog plugin from CKEditor 4 presets.

We strongly encourage everyone to choose one of the other available spellchecking solutions – Spell Check As You Type (SCAYT) or WProofreader.

Fixed issues:

#5097: [Chrome] Fixed: Incorrect conversion of points to pixels while using CKEDITOR.tools.convertToPx().

CKEditor 4.17.1

Highlights:

Due to a regression in CKEeditor 4.17.0 version that was only revealed after the release and affected a limited area of operation, CSS assets loaded via relative links started to point into invalid location when loaded from external resources.

We have therefore decided to immediately release CKEditor 4.17.1 that fixed this problem. If you have already upgraded to v4.17.0, make sure to upgrade to v4.17.1 to avoid this regression.

Fixed issues:

#4979: Fixed: Added cache key in #4761 started to breaking relative links for external CSS resources. The fix has been reverted and will be corrected in the next editor version.
