CVE-2026-88043
HighCVSS 7.2Exploitation Probability (EPSS)
Low risk14th percentile - higher than 14% of all known CVEs
Summary
The Mang Board WP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'data_type' parameter in all versions up to, and including, 2.4.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Risk Assessment
An unauthenticated attacker can inject malicious scripts that execute in a user's browser, potentially leading to session theft, redirects, or other attacks. This risk affects all WordPress sites using this plugin.
Recommendation
Update the Mang Board WP plugin to a version later than 2.4.0 as soon as it becomes available. Until then, consider disabling the plugin or deploying traffic filtering (WAF).

The Mang Board WP plugin for WordPress is vulnerable to Missing Authorization via Authentication Cookie Forgery in all versions up to, and including, 2.3.7.

This makes it possible for authenticated attackers, with subscriber-level access and above, to forge administrator authentication cookies and change administrator passwords to achieve complete site takeover.
