What is CVE-2026-7373?
CVE-2026-7373 is a high-severity vulnerability in Rapid7 Metasploit Pro, published on 15 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
Rapid7 Metasploit Pro is vulnerable to a local privilege escalation attack that allows a user to gain SYSTEM level control of a Windows host. When started the metasploitPostgreSQL service would start the postgres.exe child process which would in turn load an OpenSSL configuration file from a static location. This static location would be writable by a pre-existing "vagrant" user, if they already existed on the system. Metasploit does not create local accounts, an Administrator would need to create it. By planting a crafted openssl.cnf file an attacker can trick the high-privilege service into executing arbitrary commands. This effectively permits the unprivileged vagrant user to bypass security controls and achieve a full host compromise under the agent's SYSTEM level access.
