CVE-2025-36546 describes a high-severity vulnerability in F5OS-A and F5OS-C systems where SSH key-based authentication for the root user remains active even after Appliance Mode is enabled, bypassing intended security restrictions. With a CVSS score of 8.1, this vulnerability allows an unauthenticated attacker with the root user's private SSH key to achieve full compromise (confidentiality, integrity, and availability) of the system, though the attack complexity is high due to the prerequisite of obtaining the private key. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
