Description

This security bulletin contains information about 1 vulnerability.


1) Cross-site scripting (CVE-ID: N/A)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]


The vulnerability allows a remote user to execute arbitrary JavaScript in the embedding application's origin, disclose sensitive data, and perform actions as the victim.

The vulnerability exists due to stored cross-site scripting in Jodit Editor's iframe plugin when Document.write() processes full HTML documents before safeHTML sanitization with iframe and editHTMLDocumentMode enabled. A remote user can supply a document containing a <script> element that another user opens in the editor to execute JavaScript and access the parent page through the default unsandboxed, same-origin iframe.


Remediation

Install update from vendor's website.
