tinymce@5.10.4 vulnerabilities

tinymce is a web-based JavaScript HTML WYSIWYG editor control.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) when using the noneditable_regexp option on an element whose content does not match the regex. An attacker can inject malicious scripts into HTML attributes that are executed when extracted from the editor.

Upgrade tinymce to version 6.8.4, 7.2.0 or higher.

tinymce is a web-based JavaScript HTML WYSIWYG editor control.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) when parsing noscript elements in the editor. An attacker can bypass sanitization by placing malicious code in noscript elements.

tinymce is a web-based JavaScript HTML WYSIWYG editor control.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via mutation of inner HTML. An attacker can inject malicious scripts that pass the initial sanitization layer when the content is parsed into the editor body, but can trigger XSS when the special internal marker is removed from the content and re-parsed. Text nodes in some parents are not sufficiently escaped upon serialization and can contain a special character reserved as an internal marker.

Upgrade tinymce to version 5.10.9, 6.7.3 or higher.

tinymce is a web-based JavaScript HTML WYSIWYG editor control.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the core undo and redo functionality. An attacker can exploit this vulnerability by passing a carefully-crafted HTML snippet that bypasses the sanitisation layer, is manipulated as a string by internal trimming functions, and is stored in the undo stack. If the HTML snippet is restored from the undo stack, the reparative parsing by either the browser's native DOMParser API (TinyMCE 6) or the SaxParser API (TinyMCE 5) mutates the HTML maliciously.

Upgrade tinymce to version 5.10.8, 6.7.1 or higher.

tinymce is a web-based JavaScript HTML WYSIWYG editor control.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the Notification Manager API due to improper input sanitization. An attacker can execute arbitrary JavaScript when a notification is presented in the UI for the current user by inserting carefully crafted malicious content into the editor and triggering a notification.

Upgrade tinymce to version 5.10.8, 6.7.1 or higher.

tinymce is a web-based JavaScript HTML WYSIWYG editor control.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS) due to improper user-input sanitization in the alert and confirm dialogs when these dialogs were provided with malicious HTML content. This can occur in plugins that use the alert or confirm dialogs, such as in the image plugin, which presents these dialogs when certain errors occur.

Upgrade tinymce to version 5.10.7, 6.3.1 or higher.
