MEDIUM

Sports Club Management <= 1.12.9 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'before' Attribute

Title source: cna
STIX 2.1

Description

The Sports Club Management plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'before' and 'after' attributes of the `scm_member_data` shortcode in all versions up to, and including, 1.12.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
