CVE-2026-4871: Pstruik Sports Club Management

Medium severity, CVSS 6.4. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Pstruik Sports Club Management: up to and including 1.12.9
