CVE-2026-90884 brechtvds CVE debrief

Who should care

Defenders responsible for WordPress installations with the WP Recipe Maker plugin should assess exposure and prioritize verification and remediation efforts due to the potential security risks associated with Stored Cross-Site Scripting vulnerability. This includes reviewing plugin versions, restricting Contributor-level access and above, and implementing additional security measures to prevent exploitation.

Why it matters

The WP Recipe Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting, allowing authenticated attackers to inject arbitrary web scripts, which can lead to security risks for WordPress installations with the plugin.

• Authenticated attackers with Contributor-level access and above can inject arbitrary web scripts
• Injected scripts execute when a user accesses an injected page
• Defenders must verify and update WP Recipe Maker plugin versions
• Defenders should restrict Contributor-level access and above

Technical summary

The WP Recipe Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'notes' parameter in all versions up to, and including, 10.8.1 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.

Defensive priority

Defenders should prioritize verifying and updating WP Recipe Maker plugin versions, monitoring for suspicious activity, and restricting Contributor-level access and above.

Recommended defensive actions

• Verify and update WP Recipe Maker plugin versions to the latest version
• Monitor for suspicious activity and restrict Contributor-level access and above
• Implement input sanitization and output escaping for the 'notes' parameter
• 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
