TinyMCE Vulnerability Remediation Guidance

CVE Description Full list of Impacted Versions Fix
CVE-2024-38357 TinyMCE is an open source rich text editor. A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s content parsing code. This allowed specially crafted noscript elements containing malicious code to be executed when that content was loaded into the editor. This vulnerability has been patched in TinyMCE 7.2.0, TinyMCE 6.8.4 and TinyMCE 5.11.0 LTS by ensuring that content within noscript elements are properly parsed. Users are advised to upgrade. There are no known workarounds for this vulnerability. 4.0.28, 4.0.21, 6.1.0, 6.3.0, 6.7.2, 6.0.0, 6.4.1, 6.2.0 (Show all) Major → 7.2.0
CVE-2024-38356 TinyMCE is an open source rich text editor. A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s content extraction code. When using the `noneditable_regexp` option, specially crafted HTML attributes containing malicious code were able to be executed when content was extracted from the editor. This vulnerability has been patched in TinyMCE 7.2.0, TinyMCE 6.8.4 and TinyMCE 5.11.0 LTS by ensuring that, when using the `noneditable_regexp` option, any content within an attribute is properly verified to match the configured regular expression before being added. Users are advised to upgrade. There are no known workarounds for this vulnerability. 4.0.28, 4.0.21, 6.1.0, 6.3.0, 6.7.2, 6.0.0, 6.4.1, 6.2.0 (Show all) Major → 7.2.0
CVE-2024-29881 TinyMCE is an open source rich text editor. A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s content loading and content inserting code. A SVG image could be loaded though an `object` or `embed` element and that image could potentially contain a XSS payload. This vulnerability is fixed in 6.8.1 and 7.0.0. 4.0.28, 4.0.21, 6.1.0, 6.3.0, 6.7.2, 6.0.0, 6.4.1, 6.2.0 (Show all) Major → 7.2.0
CVE-2024-29203 TinyMCE is an open source rich text editor. A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s content insertion code. This allowed `iframe` elements containing malicious code to execute when inserted into the editor. These `iframe` elements are restricted in their permissions by same-origin browser protections, but could still trigger operations such as downloading of malicious assets. This vulnerability is fixed in 6.8.1. 4.0.28, 4.0.21, 6.1.0, 6.3.0, 6.7.2, 6.0.0, 6.4.1, 6.2.0 (Show all) Major → 7.2.0
CVE-2024-21911 TinyMCE versions before 5.6.0 are affected by a stored cross-site scripting vulnerability. An unauthenticated and remote attacker could insert crafted HTML into the editor resulting in arbitrary JavaScript execution in another user's browser. 4.0.28, 4.0.21, 5.2.1, 5.1.6, 5.0.14, 5.3.1, 5.3.0, 5.5.0 (Show all) Major → 7.2.0
CVE-2024-21910 TinyMCE versions before 5.10.0 are affected by a cross-site scripting vulnerability. A remote and unauthenticated attacker could introduce crafted image or link URLs that would result in the execution of arbitrary JavaScript in an editing user's browser. 4.0.28, 4.0.21, 5.9.2, 5.9.1, 5.7.0, 5.9.0, 5.6.0, 5.2.1 (Show all) Major → 7.2.0
CVE-2024-21908 TinyMCE versions before 5.9.0 are affected by a stored cross-site scripting vulnerability. An unauthenticated and remote attacker could insert crafted HTML into the editor resulting in arbitrary JavaScript execution in another user's browser. 4.0.28, 4.0.21, 5.7.0, 5.6.0, 5.2.1, 5.1.6, 5.0.14, 5.3.1 (Show all) Major → 7.2.0
CVE-2023-48219 TinyMCE is an open source rich text editor. A mutation cross-site scripting (mXSS) vulnerability was discovered in TinyMCE’s core undo/redo functionality and other APIs and plugins. Text nodes within specific parents are not escaped upon serialization according to the HTML standard. If such text nodes contain a special character reserved as an internal marker, they can be combined with other HTML patterns to form malicious snippets. These snippets pass the initial sanitisation 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. his vulnerability has been patched in TinyMCE versions 6.7.3 and 5.10.9. Users are advised to upgrade. There are no known workarounds for this vulnerability. 4.0.28, 4.0.21, 6.1.0, 6.3.0, 6.7.2, 6.0.0, 6.4.1, 6.2.0 (Show all) Major → 7.2.0
CVE-2023-45819 TinyMCE is an open source rich text editor. A cross-site scripting (XSS) vulnerability was discovered in TinyMCE’s Notification Manager API. The vulnerability exploits TinyMCE's unfiltered notification system, which is used in error handling. The conditions for this exploit requires carefully crafted malicious content to have been inserted into the editor and a notification to have been triggered. When a notification was opened, the HTML within the text argument was displayed unfiltered in the notification. The vulnerability allowed arbitrary JavaScript execution when an notification presented in the TinyMCE UI for the current user. This issue could also be exploited by any integration which uses a TinyMCE notification to display unfiltered HTML content. This vulnerability has been patched in TinyMCE 5.10.8 and TinyMCE 6.7.1 by ensuring that the HTML displayed in the notification is sanitized, preventing the exploit. Users are advised to upgrade. There are no known workarounds for this vulnerability. 4.0.28, 4.0.21, 6.1.0, 6.3.0, 6.0.0, 6.4.1, 6.2.0, 6.0.1 (Show all) Major → 7.2.0
CVE-2023-45818 TinyMCE is an open source rich text editor. A mutation cross-site scripting (mXSS) vulnerability was discovered in TinyMCE’s core undo and redo functionality. When a carefully-crafted HTML snippet passes the XSS sanitisation layer, it is manipulated as a string by internal trimming functions before being stored in the undo stack. If the HTML snippet is restored from the undo stack, the combination of the string manipulation and reparative parsing by either the browser's native [DOMParser API](https://developer.mozilla.org/en-US/docs/Web/API/DOMParser) (TinyMCE 6) or the SaxParser API (TinyMCE 5) mutates the HTML maliciously, allowing an XSS payload to be executed. This vulnerability has been patched in TinyMCE 5.10.8 and TinyMCE 6.7.1 by ensuring HTML is trimmed using node-level manipulation instead of string manipulation. Users are advised to upgrade. There are no known workarounds for this vulnerability. 4.0.28, 4.0.21, 6.1.0, 6.3.0, 6.0.0, 6.4.1, 6.2.0, 6.0.1 (Show all) Major → 7.2.0
CVE-2022-23494 tinymce is an open source rich text editor. A cross-site scripting (XSS) vulnerability was discovered 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. The vulnerability allowed arbitrary JavaScript execution when an alert presented in the TinyMCE UI for the current user. This vulnerability has been patched in TinyMCE 5.10.7 and TinyMCE 6.3.1 by ensuring HTML sanitization was still performed after unwrapping invalid elements. Users are advised to upgrade to either 5.10.7 or 6.3.1. Users unable to upgrade may ensure the the `images_upload_handler` returns a valid value as per the images_upload_handler documentation. 4.0.28, 4.0.21, 6.1.0, 6.3.0, 6.0.0, 6.2.0, 6.0.1, 6.1.2 (Show all) Major → 7.2.0
CVE-2020-17480 TinyMCE before 4.9.7 and 5.x before 5.1.4 allows XSS in the core parser, the paste plugin, and the visualchars plugin by using the clipboard or APIs to insert content into the editor. 4.0.28, 4.0.21, 5.0.14, 5.0.13, 4.9.5, 5.0.9, 4.9.2, 4.8.3 (Show all) Major → 7.2.0
CVE-2020-12648 A cross-site scripting (XSS) vulnerability in TinyMCE 5.2.1 and earlier allows remote attackers to inject arbitrary web script when configured in classic editing mode. 4.0.28, 4.0.21, 5.2.1, 5.1.6, 5.0.14, 5.3.1, 5.3.0, 5.0.13 (Show all) Major → 7.2.0
CVE-2019-1010091 tinymce 4.7.11, 4.7.12 is affected by: CWE-79: Improper Neutralization of Input During Web Page Generation. The impact is: JavaScript code execution. The component is: Media element. The attack vector is: The victim must paste malicious content to media element's embed tab. 4.0.28, 4.0.21, 5.2.1, 5.1.6, 5.0.14, 5.0.13, 4.9.5, 5.0.9 (Show all) Major → 7.2.0
