CVE-2023-3587 is a low-severity vulnerability affecting Mattermost Server, where a system administrator can inadvertently grant editor access to any user with a valid sharing link for a board. This occurs because the UI fails to accurately display the updated permissions, leading to an information disclosure risk (CVSS 2.7). While the vulnerability requires high privileges to initiate, it has a low attack complexity and does not involve active exploitation, publicly available exploit code, or significant community discussion.
