**Name of the Vulnerable Software and Affected Versions** TinyMCE versions prior to 5.10.9 TinyMCE versions prior to 6.7.3 **Description** 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. The vulnerability occurs when serialised HTML content is processed before being stored in the undo stack, or when the following APIs and plugins are used: `tinymce.Editor.getContent({ format: 'raw' })`, `tinymce.Editor.resetContent()`, and the Autosave Plugin. **Recommendations** - Upgrade to TinyMCE 5.10.9 or higher for TinyMCE 5.x. - Upgrade to TinyMCE 6.7.3 or higher for TinyMCE 6.x.

**Name of the Vulnerable Software and Affected Versions** TinyMCE versions prior to 5.10.8 TinyMCE versions prior to 6.7.1 **Description** 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 (TinyMCE 6) or the SaxParser API (TinyMCE 5) mutates the HTML maliciously, allowing an XSS payload to be executed. This vulnerability also impacts related TinyMCE APIs and plugins, including `tinymce.Editor.getContent({ format: 'raw' })`, `tinymce.Editor.resetContent()`, and the Autosave Plugin. **Recommendations** * Upgrade to TinyMCE 5.10.8 or higher for TinyMCE 5.x. * Upgrade to TinyMCE 6.7.1 or higher for TinyMCE 6.x.

**Name of the Vulnerable Software and Affected Versions** Electron versions prior to 11.0.0-beta.1 Electron versions prior to 10.0.1 Electron versions prior to 9.3.0 Electron versions prior to 8.5.1 **Description** The `will-navigate` event can be bypassed when a sub-frame performs a top-frame navigation across sites. This issue can be exploited to bypass navigation restrictions. As a workaround, sandboxing all iframes using the `sandbox` attribute can prevent them from creating top-frame navigations. **Recommendations** For versions prior to 11.0.0-beta.1, update to version 11.0.0-beta.1 or later. For versions prior to 10.0.1, update to version 10.0.1 or later. For versions prior to 9.3.0, update to version 9.3.0 or later. For versions prior to 8.5.1, update to version 8.5.1 or later. As a temporary workaround, consider sandboxing all iframes using the `sandbox` attribute to prevent them from creating top-frame navigations.

**Name of the Vulnerable Software and Affected Versions** Prism versions 1.1.0 through 1.20.0 Prism Previewers plugin versions 1.10.0 through 1.20.0 Prism Previewer: Easing plugin versions 1.1.0 through 1.9.0 **Description** The easing preview of the Previewers plugin has a Cross-Site Scripting (XSS) vulnerability, allowing attackers to execute arbitrary code in Safari and Internet Explorer. This issue impacts all Safari and Internet Explorer users of Prism that use the affected plugins. **Recommendations** For Prism versions 1.1.0 through 1.20.0, update to version 1.21.0 to resolve the issue. For Prism Previewers plugin versions 1.10.0 through 1.20.0, update to version 1.21.0 to resolve the issue. For Prism Previewer: Easing plugin versions 1.1.0 through 1.9.0, update to version 1.21.0 to resolve the issue. As a temporary workaround, consider disabling the easing preview on all impacted code blocks, available for Prism v1.10.0 or newer.

**Name of the Vulnerable Software and Affected Versions** Google Chrome versions prior to 57.0.2987.98 for Mac, Windows, and Linux Google Chrome version prior to 57.0.2987.108 for Android **Description** The issue is related to insufficient policy enforcement in V8, allowing a remote attacker to spoof the location object via a crafted HTML page. This is related to information disclosure in Blink. **Recommendations** For Google Chrome versions prior to 57.0.2987.98 on Mac, Windows, and Linux, update to version 57.0.2987.98 or later. For Google Chrome version prior to 57.0.2987.108 on Android, update to version 57.0.2987.108 or later.

**Name of the Vulnerable Software and Affected Versions** ZeroClipboard versions prior to 1.3.2 **Description** The issue allows remote attackers to inject arbitrary web script or HTML via vectors related to certain SWF query parameters, specifically `loaderInfo.parameters`. This enables attackers to perform cross-site scripting (XSS) attacks. **Recommendations** For versions prior to 1.3.2, update to version 1.3.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the `loaderInfo.parameters` to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** Google Chrome versions prior to 31.0.1650.48 **Description** The issue involves multiple unspecified vulnerabilities that could allow attackers to execute arbitrary code or have other impacts via unknown vectors. **Recommendations** For versions prior to 31.0.1650.48, update to version 31.0.1650.48 or later to resolve the issue.

Cross-site scripting (XSS) vulnerability in MediaWiki before 1.16.5, when Internet Explorer 6 or earlier is used, allows remote attackers to inject arbitrary web script or HTML via an uploaded file accessed with a dangerous extension such as .shtml at the end of the query string, in conjunction with a modified URI path that has a %2E sequence in place of the . (dot) character. NOTE: this vulnerability exists because of an incomplete fix for CVE-2011-1578 and CVE-2011-1587.
