Description

This security bulletin contains information about 1 vulnerability.


1) Cross-site scripting (CVE-ID: CVE-2026-40171)

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

CVSSv4: 4.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]


The vulnerability allows a remote user to steal authentication tokens and execute arbitrary code.

The vulnerability exists due to cross-site scripting in the help extension command linker functionality when rendering malicious notebook content. A remote privileged user can craft a malicious notebook file and induce a single click on attacker-controlled elements to steal authentication tokens and execute arbitrary code.

User interaction is required to open a malicious notebook file and click an element made to appear indistinguishable from a legitimate control.
