- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

## Affected

- Rapid7 Metasploit Pro: through 4.21.2

## Description

Rapid7 Metasploit Pro versions 4.21.2 and lower suffer from a stored cross site scripting vulnerability, due to a lack of JavaScript request string sanitization. Using this vulnerability, an authenticated attacker can execute arbitrary HTML and script code in the target browser against another Metasploit Pro user using a specially crafted request. Note that in most deployments, all Metasploit Pro users tend to enjoy privileges equivalent to local administrator.
