Administrative FortiCloud SSO authentication bypass
IR Number FG-IR-26-060
Published Date Jan 27, 2026
Component GUI
Severity Critical
CVSSv3 Score 9.4
Impact Improper access control
CVE ID CVE-2026-24858
Summary
An Authentication Bypass Using an Alternate Path or Channel vulnerability [CWE-288] in FortiOS, FortiManager, FortiAnalyzer may allow an attacker with a FortiCloud account and a registered device to log into other devices registered to other accounts, if FortiCloud SSO authentication is enabled on those devices.
Please note that the FortiCloud SSO login feature is not enabled in default factory settings. However, when an administrator registers the device to FortiCare from the device's GUI, unless the administrator disables the toggle switch "Allow administrative login using FortiCloud SSO" in the registration page, FortiCloud SSO login is enabled upon registration.
This vulnerability was found being exploited in the wild by two malicious FortiCloud accounts, which were locked out on 2026-01-22. In order to protect its customers from further exploit, Fortinet disabled FortiCloud SSO on FortiCloud side on 2026-01-26. It was re-enabled on 2026-01-27 and no longer supports login from devices running vulnerable versions. Consequently, customers must upgrade to the latest versions listed below for the FortiCloud SSO authentication to function.

CVE-2026-23745
Description
node-tar is a Tar for Node.js. The node-tar library (<= 7.5.2) fails to sanitize the linkpath of Link (hardlink) and SymbolicLink entries when preservePaths is false (the default secure behavior). This allows malicious archives to bypass the extraction root restriction, leading to Arbitrary File Overwrite via hardlinks and Symlink Poisoning via absolute symlink targets. This vulnerability is fixed in 7.5.3.

n8n Vulnerable to RCE via Arbitrary File Write
Impact
n8n is affected by an authenticated Remote Code Execution (RCE) vulnerability.
Under certain conditions, an authenticated user may be able to cause untrusted code to be executed by the n8n service. This could result in full compromise of the affected instance.
Both self-hosted and n8n Cloud instances are impacted.
Patches
The issue has been resolved in n8n version 1.121.3.
Workarounds
If upgrading is not immediately possible, administrators can reduce exposure by disabling the Git node and limiting access for untrusted users.
