Organizations using Fortinet technology should review both advisories directly in the vendor's PSIRT portal to determine product exposure, patch availability, and any required mitigations. Security teams should prioritize asset inventory checks, validate whether impacted Fortinet deployments are present in their environment, and apply vendor-recommended updates or compensating controls once the advisory details are confirmed.

Fortinet released fixes for two **critical** vulnerabilities that could let remote, unauthenticated attackers run unauthorized code or commands on exposed systems. The first, **`CVE-2026-44277`**, is an improper access control flaw in **FortiAuthenticator** with a **CVSS 9.1** rating; it affects versions **8.0.0**, **8.0.2**, **6.6.0-6.6.8**, and **6.5.0-6.5.6**, and was patched in **8.0.3**, **6.6.9**, and **6.5.7**. Fortinet said the issue stems from insufficient authorization checks on API endpoints and could allow unauthorized API access, privilege escalation, and command execution, while **FortiAuthenticator Cloud is not affected**. Fortinet also disclosed **`CVE-2026-26083`**, a **CVSS 9.1** missing-authorization flaw in the **FortiSandbox** Web UI that impacts **FortiSandbox**, **FortiSandbox Cloud**, and **FortiSandbox PaaS**, potentially enabling arbitrary code execution across on-premises and cloud deployments. Canada’s Cyber Centre warned that the advisories span multiple Fortinet products and urged administrators to review Fortinet PSIRT notices and apply updates promptly. Public reporting said Fortinet had not observed either flaw being exploited in the wild at disclosure, but the breadth of affected security infrastructure and Fortinet’s history of high-value exploitation have increased urgency around patching exposed appliances.

Italian and Colombian cyber authorities issued alerts on vulnerabilities affecting **Fortinet** products, with CSIRT Italia detailing multiple information-disclosure flaws in **FortiSandbox** and **FortiAuthenticator** and warning that two of the issues are rated **high severity**. The disclosed weaknesses could allow a malicious user to access sensitive information on affected systems, expanding risk for organizations that rely on these appliances for authentication and sandboxing functions. CSIRT Italia said the affected products span specific version ranges and urged administrators to apply the updates referenced in Fortinet security bulletins. Separate **COLCERT** alerts also warned of **critical vulnerabilities** in Fortinet products, reinforcing the need for immediate review of exposed deployments even though the Colombian notices provided limited technical detail on affected versions, CVE identifiers, or exploitation activity.

Fortinet released security updates for vulnerabilities affecting **FortiOS**, **FortiProxy**, **FortiSandbox**, FortiSandbox Cloud, and FortiSandbox PaaS. Italy's national CSIRT reported that the set includes one critical and one high-severity issue that could expose sensitive information; affected FortiOS and FortiProxy versions include 7.6.x before 7.6.7, while affected FortiSandbox releases include 5.0.x before 5.0.6 and 4.4.x before 4.4.9. One disclosed issue, **CVE-2026-26084**, is a high-severity improper-access-control flaw in the FortiSandbox web interface, rated **CVSS 8.9**. Unauthenticated remote attackers could use crafted HTTP requests to reach internal API endpoints and retrieve sensitive information without credentials or user interaction. Fortinet reported no evidence of active exploitation and credited internal researcher Adham El Karn; the Canadian Centre for Cyber Security also urged administrators to review Fortinet PSIRT advisories and promptly apply relevant updates across affected Fortinet products.
