Multiple improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerabilities [CWE-78] in FortiManager CLI may allow a privileged attacker to execute unauthorized code or commands via crafted CLI requests.

CVE-2025-26466A flaw was found in the OpenSSH package. For each ping packet the SSH server receives, a pong packet is allocated in a memory buffer and stored in a queue of packages. It is only freed when the server/client key exchange has finished. A malicious client may keep sending such packages, leading to an uncontrolled increase in memory consumption on the server side. Consequently, the server may become unavailable, resulting in a denial of service attack.

An improper neutralization of special elements used in an OS command ('OS Command Injection') vulnerability [CWE-78] in FortiAnalyzer, FortiManager, FortiAnalyzer BigData, FortiAnalyzer Cloud and FortiManager Cloud GUI may allow an authenticated privileged attacker to execute unauthorized code or commands via crafted HTTPS or HTTP requests.

An improper privilege management vulnerability [CWE 269] in FortiManager and FortiAnalyzer may allow a local attacker to escalate their privileges by abusing incorrect filesystem permissions

A use of externally-controlled format string vulnerability [CWE-134] in FortiAnalyzer fazsvcd daemon may allow a remote privileged attacker with admin profile to execute arbitrary code or commands via specially crafted requests.
