An Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability [CWE-89] in FortiAnalyzer and FortiAnalyzer-BigData API may allow an authenticated attacker to execute unauthorized code or commands via specifically crafted requests.

Multiple improper neutralization of special elements used in an os command ('os command injection') in Fortinet FortiManager, FortiAnalyzer versions 7.4.0 through 7.4.2 7.2.0 through 7.2.5 and 7.0.0 through 7.0.12 and 6.4.0 through 6.4.14 and 6.2.0 through 6.2.12 and 6.0.0 through 6.0.12 and 5.6.0 through 5.6.11 and 5.4.0 through 5.4.7 and 5.2.0 through 5.2.10 and 5.0.0 through 5.0.12 and 4.3.4 through 4.3.8 allows 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.

A client-side enforcement of server-side security [CWE-602] vulnerability in FortiManager and FortiAnalyzer may allow a remote attacker with low privileges to access a privileged web console via client side code execution.
