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.

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.

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.

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.

The TinyMCE Custom Styles WordPress plugin before 1.1.4 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

Auth. (admin+) Stored Cross-Site Scripting (XSS) vulnerability in Tim Reeves & David Stöckl TinyMCE Custom Styles plugin <= 1.1.2 versions.

The Custom TinyMCE Shortcode Button WordPress plugin through 1.1 does not sanitise and escape the PHP_SELF variable before outputting it back in an attribute in an admin page, leading to Reflected Cross-Site Scripting.

Cross-site request forgery (CSRF) vulnerability in the TinyMCE Color Picker plugin before 1.2 for WordPress allows remote attackers to hijack the authentication of unspecified users for requests that change plugin settings via unknown vectors. NOTE: some of these details are obtained from third party information.

The TinyMCE Color Picker plugin before 1.2 for WordPress does not properly check permissions, which allows remote attackers to modify plugin settings via unspecified vectors. NOTE: some of these details are obtained from third party information.

The bbcode plugin in TinyMCE 3.5.8 does not properly enforce the TinyMCE security policy for the (1) encoding directive and (2) valid_elements attribute, which allows attackers to conduct cross-site scripting (XSS) attacks via application-specific vectors, as demonstrated using a textarea element.
