Stack-based buffer overflow in Fortinet FortiOS, FortiPAM, FortiProxy, and FortiSASE enables arbitrary code execution for a privileged authenticated attacker capable of bypassing ASLR and stack canary protections via crafted HTTP requests. The CVSS temporal metric E:P confirms proof-of-concept exploit code exists, and RL:O confirms an official patch has been released by Fortinet (advisory FG-IR-26-148). This vulnerability is not listed in CISA KEV at time of analysis, and the dual prerequisites of privileged access plus memory-protection bypass substantially constrain real-world exploitability despite the critical CIA impact triad.
Open redirect vulnerability in Fortinet FortiOS, FortiProxy, and FortiSASE enables unauthenticated attackers on an adjacent network segment to redirect authenticated users to attacker-controlled sites via crafted HTTP requests. The attack surface is substantially constrained by the adjacent-network-only vector (AV:A), high attack complexity (AC:H), and mandatory user interaction (UI:R), yielding a CVSS 2.6 Low severity score. No public exploit identified at time of analysis, and EPSS at 0.01% (1st percentile) confirms negligible observed exploitation pressure. A Siemens PSIRT advisory (SSA-864900) indicates this vulnerability also affects Siemens products embedding Fortinet components.
Reflected cross-site scripting (XSS) in FortiOS, FortiProxy, and FortiSASE allows unauthenticated remote attackers to inject and execute malicious scripts in a victim's browser by tricking them into clicking a crafted HTTP request link. The vulnerability spans a wide range of FortiOS versions from 6.4 through 7.6.3 and all FortiProxy 7.x branches, meaning a large installed base of Fortinet network security appliances is affected. A Siemens CERT advisory (SSA-864900) indicates this vulnerability also affects Siemens products that embed Fortinet components, broadening organizational impact. No public exploit or CISA KEV listing has been identified at time of analysis.
An Exposure of Sensitive Information to an Unauthorized Actor vulnerability [CWE-200] in FortiOS version 7.6.0, version 7.4.7 and below, 7.2 all versions, 7.0 all versions, 6.4 all versions SSL-VPN web-mode may allow an authenticated user to access full SSL-VPN settings via crafted URL.
