What is CVE-2026-92712?
CVE-2026-92712 is a medium-severity cross-site scripting vulnerability in rockiger ReactPress – Create React App for WordPress, published on 30 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
The ReactPress – Create React App for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'permalink' parameter in all versions up to, and including, 3.4.0 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. This is possible because the permalink parameter is only passed through sanitize_url(), which does not prevent fetching attacker-controlled remote URLs whose response body — including script tags and event-handler attributes — is written verbatim to disk via file_put_contents().
