WP Block Pack can let attackers insert harmful code

CVE-2025-23874 · published 1 year ago
Summary

The WP Block Pack add‑on for WordPress (versions up to 1.1.6) does not properly clean the data it shows on web pages. This means a malicious link could cause harmful scripts to run in a visitor’s browser, potentially exposing personal information or taking over the session. Update the add‑on to a newer version or remove it until a fix is available.
