CVE-2026-91862 jetmonsters CVE debrief

Who should care

Defenders responsible for WordPress installations with the Getwid – Gutenberg Blocks plugin, particularly those with contributor-level access and above, should assess exposure and prioritize verification and updates.

Why it matters

The vulnerability in Getwid – Gutenberg Blocks plugin versions up to 3.0.1 allows authenticated attackers to inject arbitrary web scripts, potentially leading to security risks. Defenders should prioritize verification and updates, and restrict contributor-level access to trusted users.

• Potential injection of arbitrary web scripts in pages.
• Execution of injected scripts when users access affected pages.
• Verification of plugin version and restriction of contributor-level access are necessary.

Technical summary

The Getwid – Gutenberg Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'data-image-points' parameter in all versions up to, and including, 3.0.1. This is due to insufficient input sanitization and output escaping, allowing authenticated attackers with contributor-level access and above to inject arbitrary web scripts in pages. Defenders should prioritize verifying and updating the plugin, restricting access, and monitoring for suspicious activity to mitigate potential security risks.

Defensive priority

Defenders should prioritize verifying and updating the Getwid – Gutenberg Blocks plugin to a version beyond 3.0.1 if possible, and restrict contributor-level access and above to trusted users.

Recommended defensive actions

• Verify and update the Getwid – Gutenberg Blocks plugin to a version beyond 3.0.1 if possible.

• 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.
