      <title>GHSA-v98h-vmpc-fpqv — TinyMCE Cross-Site Scripting (XSS) vulnerability through `mce:protected` comments</title>
      <link>https://cve.radiocsirt.org/vuln/ghsa-v98h-vmpc-fpqv</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; npm: tinymce, NuGet: TinyMCE, Packagist: tinymce/tinymce&lt;/p&gt;
&lt;p&gt;### Impact
Stored XSS vulnerability via forged mce:protected comments. Allows attackers to bypass sanitization and inject scripts that execute when content is restored. Impacts users who utilize the protect option.&lt;/p&gt;
&lt;p&gt;### Patches
Patched by validating decoded mce:protected content against configured protect regex rules before restoring. Users should upgrade to the latest patched version.&lt;/p&gt;
&lt;p&gt;### Workarounds
No official workaround available.&lt;/p&gt;
&lt;p&gt;### Fix
To avoid this vulnerability:&lt;/p&gt;
&lt;p&gt;Upgrade to TinyMCE 8.5.1 or higher.
Upgrade to TinyMCE 7.9.3 or higher.
Upgrade to TinyMCE 5.11.1 LTS or higher for TinyMCE 5.x (only available as part of commercial [long-term support](https://www.tiny.cloud/long-term-support/) contract).&lt;/p&gt;
&lt;p&gt;### Acknowledgements
Tiny thanks [Ivan Babenko](https://github.com/he1d3n) for their help identifying this vulnerability.&lt;/p&gt;</description>
