CKEditor4 low-risk cross-site scripting (XSS) vulnerability linked to potential domain takeover
### Affected Packages
The issue impacts only editor instances with enabled [version notifications](https://ckeditor.com/docs/ckeditor4/latest/api/CKEDITOR_config.html#cfg-versionCheck).
Please note that this feature is disabled by default in all CKEditor 4 LTS versions. Therefore, if you use CKEditor 4 LTS, it is highly unlikely that you are affected by this vulnerability. If you are unsure, please [contact us](mailto:security@cksource.com).
### Impact
A theoretical vulnerability has been identified in CKEditor 4.22 (and above). In a highly unlikely scenario where an attacker gains control over the https://cke4.ckeditor.com domain, they could potentially execute an attack on CKEditor 4 instances. Although the vulnerability is purely hypothetical, we have addressed it in CKEditor 4.25.0-lts to ensure compliance with security best practices.
### Patches
The issue has been recognized and patched. The fix is available in version 4.25.0-lts.

Code Snippet GeSHi plugin in CKEditor 4 has reflected cross-site scripting (XSS) vulnerability
### Affected packages
The vulnerability has been discovered in [Code Snippet GeSHi](https://ckeditor.com/cke4/addon/codesnippetgeshi) plugin. All integrators that use [GeSHi syntax highlighter](https://github.com/GeSHi/geshi-1.0) on the backend side can be affected.
### Impact
A potential vulnerability has been discovered in CKEditor 4 [Code Snippet GeSHi](https://ckeditor.com/cke4/addon/codesnippetgeshi) plugin. The vulnerability allowed a reflected XSS attack by exploiting a flaw in the [GeSHi syntax highlighter library](https://github.com/GeSHi/geshi-1.0) hosted by the victim.
The GeSHi library was included as a vendor dependency in CKEditor 4 source files. In a specific scenario, an attacker could craft a malicious script that could be executed by sending a request to the GeSHi library hosted on a PHP web server.
### Patches
The [GeSHi library](https://github.com/GeSHi/geshi-1.0) is no longer actively maintained. Due to the lack of ongoing support and updates, potential security vulnerabilities have been identified with its continued use. To mitigate these risks and enhance the overall security of the CKEditor 4, we have decided to completely remove the GeSHi library as a dependency. This change aims to maintain a secure environment and reduce the risk of any security incidents related to outdated or unsupported software.
To integrators who still want to use the GeSHi syntax highlighter, we recommend manually adding the [GeSHi library](https://github.com/GeSHi/geshi-1.0) . Please be aware of and understand the potential security vulnerabilities associated with its use.
The fix is be available in version 4.25.0-lts.
### Acknowledgements
The CKEditor 4 team would like to thank [Jiasheng He](https://github.com/Hebing123) from Qihoo 360 for recognizing and reporting this vulnerability.
