CVE-2026-8625 dearhive CVE debrief

Who should care

Defenders responsible for WordPress installations with the Dear Flipbook plugin should assess exposure and prioritize verification and potential updates. This includes reviewing the plugin's current version, identifying contributors with access, and monitoring for potential exploitation attempts.

Why it matters

The Dear Flipbook plugin for WordPress is vulnerable to Stored Cross-Site Scripting, allowing authenticated attackers to inject arbitrary web scripts. Defenders should prioritize verification and updates, and monitor for potential exploitation attempts.

• Authenticated attackers with contributor-level access can inject arbitrary web scripts
• Injected scripts can execute on pages accessed by users
• Defenders must verify and update the plugin to a patched version
• Exposure requires verification from official sources

Technical summary

The Dear Flipbook plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'post_content (Custom HTML block inner HTML)' parameter in all versions up to, and including, 2.4.30 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 the Dear Flipbook plugin to a patched version, if available, and monitor for potential exploitation attempts.

Recommended defensive actions

• Verify and update the Dear Flipbook plugin to a patched version, if available
• Monitor for potential exploitation attempts
• Restrict access to the plugin's settings and functionality to authorized users only
• 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
