Description

This security bulletin contains information about 1 vulnerability.


1) Cross-site request forgery (CVE-ID: CVE-2026-29784)

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to take over a Ghost site.

The vulnerability exists due to improper request binding in /session/verify when handling one-time code verification requests. A remote attacker can cause a one-time code to be used in a login session different from the requesting session to take over a Ghost site.

User interaction is required, and exploitation is only possible in some scenarios involving phishing.
