Vorant's rating weighs the evidence in the report: confirmed exploitation, victims claimed, CVSS and EPSS, and how many sources agree. It rates the report, not your assets.

> Fortinet fixed over 40 vulnerabilities, several unauthenticated and critical (CVSS up to 9.8), in FortiManager and FortiAnalyzer including cloud variants; no active exploitation reported.

## What to check

- Applies to: The 40 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation: No exploitation in the wild and no public exploit is recorded for the CVEs named.

NCSC-NL has republished a Fortinet PSIRT advisory batch covering more than 40 vulnerabilities across FortiManager, FortiAnalyzer, and related cloud/sovereign products (FortiManager Cloud, FortiAnalyzer Cloud, FortiAnalyzer-BigData, FortiSASE-Sovereign and its GUI). The flaws span a wide range of weakness classes: path traversal, OS command and argument injection, SQL and XML injection, stack- and heap-based buffer overflows, out-of-bounds write, server-side template injection, hard-coded credentials, authentication/authorization bypass, improper certificate validation within RADIUS, and unrestricted file upload. Attack vectors include crafted HTTP/HTTPS and JSON-RPC requests, OFTP packets, and manipulation of the GUI and template engine.

Severity of individual CVEs ranges widely, with several scoring in the critical band (CVE-2026-126170, CVE-2026-126261 and CVE-2026-126262 all at CVSS 9.8, and CVE-2026-126229 at 9.1), some exploitable without authentication, while others require read-only or administrative credentials. Successful exploitation could allow arbitrary code or command execution, unauthorized file read/write/delete, privilege escalation, authentication bypass, configuration tampering, and denial of service — effectively giving an attacker control over the management plane and, by extension, the Fortinet devices it administers. Both on-premises and cloud deployments are affected.

No evidence of in-the-wild exploitation is cited in this advisory. Fortinet has released updated versions for all affected products; defenders operating FortiManager or FortiAnalyzer (including cloud/sovereign variants) should prioritize patching per the referenced FortiGuard PSIRT advisories (FG-IR-26-190 through FG-IR-26-276), paying particular attention to the unauthenticated critical-severity issues, and review access controls and exposure of management interfaces to untrusted networks in the interim.
