CVE-2026-109512 kitae-park CVE debrief

Who should care

Defenders responsible for WordPress installations with the Mang Board plugin should assess exposure and prioritize verification and remediation efforts. This includes reviewing the plugin's version, verifying the presence of the vulnerability, and updating to a fixed version if available. Additionally, defenders should ensure that input sanitization and output escaping are properly implemented and monitor for suspicious activity.

Why it matters

The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting, allowing authenticated attackers to inject arbitrary web scripts. Defenders should prioritize verifying and updating the plugin, ensuring proper input sanitization and output escaping, and monitoring for suspicious activity.

• Authenticated attackers with subscriber-level access and above can inject arbitrary web scripts
• Injected scripts can execute on pages accessed by users
• Input sanitization and output escaping are not properly implemented

Technical summary

The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content' parameter in all versions up to, and including, 2.4.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Defensive priority

Defenders should prioritize verifying and updating the Mang Board plugin to a fixed version, if available, and ensure that input sanitization and output escaping are properly implemented.

Recommended defensive actions

• Verify and update the Mang Board plugin to a fixed version, if available
• Ensure that input sanitization and output escaping are properly implemented
• Monitor for suspicious activity and implement compensating controls
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes
