CVE-2026-23573

Published Jul 14, 2026 CVSS 3.1 · 6.1 Medium EPSS < 1% KEV · Not listed

Description

An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability [CWE-79] vulnerability in Fortinet FortiOS 7.6.0 through 7.6.6, FortiOS 7.4 all versions, FortiOS 7.2 all versions, FortiPAM 1.8.0, FortiPAM 1.7 all versions, FortiPAM 1.6 all versions, FortiPAM 1.5 all versions, FortiPAM 1.4 all versions, FortiPAM 1.3 all versions, FortiPAM 1.2 all versions, FortiPAM 1.1 all versions, FortiPAM 1.0 all versions, FortiProxy 7.4.0 through 7.4.3, FortiProxy 7.2.0 through 7.2.9 may allow an authenticated remote user to execute code or commands via crafted requests.

Analysis

Technical impact

The vulnerability is an improper neutralization of input during web page generation (Cross‑Site Scripting) found in several Fortinet devices. An authenticated remote user can craft requests that contain malicious scripts, which the firmware fails to sanitize before rendering in a browser context. Exploitation can lead to arbitrary code execution or command execution on the device, thereby compromising the confidentiality, integrity, and availability of the system.

Affected Systems

Affected products include Fortinet FortiOS (versions 7.6.0 through 7.6.6, all 7.4 releases, all 7.2 releases), FortiPAM (all versions up to 1.8.0), and FortiProxy (versions 7.4.0 through 7.4.3 and 7.2.0 through 7.2.9).

Risk and Exploitability

The CVSS score of 6.1 indicates a medium severity, while the EPSS score of less than 1% suggests a low probability of exploitation in the current environment. The vulnerability is not listed in the CISA KEV catalog. Attackers would need authenticated access to the device and would leverage crafted web requests that are not properly sanitized. Although the potential impact is high, the likelihood of a successful exploit remains low at this time.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Remediation

Vendor Solution

Upgrade to FortiOS version 8.0.0 or above Upgrade to FortiOS version 7.6.7 or above Upgrade to FortiProxy version 7.4.4 or above Upgrade to FortiProxy version 7.2.10 or above Upgrade to FortiProxy version 7.0.17 or above Upgrade to FortiPAM version 1.9.0 or above Upgrade to FortiPAM version 1.8.1 or above Fortinet remediated this issue in FortiSASE version 26.1.1 and hence customers do not need to perform any action. Upgrade to FortiSwitchManager version 7.2.5 or above Upgrade to FortiSwitchManager version 7.0.3 or above

OpenCVE Recommended Actions

Upgrade FortiOS firmware to at least version 8.0.0 or 7.6.7 to patch the XSS flaw.
Update the FortiProxy package to version 7.4.4 or newer (or 7.2.10 or newer).
Ensure FortiPAM is upgraded to version 1.9.0 or higher (or at least 1.8.1).
Upgrade FortiSwitchManager firmware to version 7.2.5 or newer (or 7.0.3 or newer).
FortiSASE customers using version 26.1.1 already have the fix; no action is required.
