CVE-2026-100158 elvinhaci CVE debrief

Who should care

WordPress administrators and users with subscriber-level access and above should assess their exposure and take steps to prevent exploitation. This includes verifying the version of the SQL Chart Builder plugin, restricting access to the plugin's settings and functionality, and monitoring for suspicious activity.

Why it matters

Defenders should care about this vulnerability because it allows authenticated attackers to inject arbitrary web scripts in pages, potentially leading to security breaches. WordPress administrators and users with subscriber-level access and above should assess their exposure and take steps to prevent exploitation.

• Authenticated attackers with subscriber-level access and above can inject arbitrary web scripts in pages.
• Injected scripts will execute whenever a user accesses an injected page.
• This vulnerability requires an administrator to have published a chart whose SQL query returns a column controllable by a lower-privileged user.

Technical summary

The SQL Chart Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'X-axis column value' parameter in all versions up to, and including, 3.0.6 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 the version of the SQL Chart Builder plugin and applying patches or updates to prevent exploitation.

Recommended defensive actions

• Verify the version of the SQL Chart Builder plugin and apply patches or updates to prevent exploitation.
• Restrict access to the plugin's settings and functionality to authorized users only.
• Monitor for suspicious activity and implement additional security measures to detect and prevent exploitation.
• 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.
