What is CVE-2023-6594?
CVE-2023-6594 is a medium-severity cross-site scripting vulnerability in maxfoundry MaxButtons – Create buttons, published on 9 Jan 2024. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
The WordPress Button Plugin MaxButtons plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 9.7.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled. Administrators can give button creation privileges to users with lower levels (contributor+) which would allow those lower-privileged users to carry out attacks.
Weakness: CWE-79
