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:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]


The vulnerability allows a remote attacker to execute arbitrary JavaScript in an editing user's browser through stored cross-site scripting.

The vulnerability exists due to delayed registration of sanitising handlers in Jodit Editor's clean-html plugin when loading stored HTML from a textarea into the live editing area. A remote attacker can supply stored HTML containing <img src="data:," onerror="alert(document.domain)"> to execute script before sanitisation, including in same-origin iframe mode where it can access the host page.


Remediation

Install update from vendor's website.
