Is xmlrpc attacks blocker safe? Known vulnerabilities and latest version

Status: Closed 2026-02-17
Known issues on record: 1
Unpatched in latest: 0

What to do

Replace it. A closed plugin gets no updates through WordPress, so any hole found from now on stays open.
Deactivate and delete it once you have a replacement (Plugins → Deactivate → Delete). Deleting removes its files; deactivating alone leaves them on the server.
If you ran a vulnerable version and something looks off (spam pages, strange admins, redirects), run the free scan, or have us clean it: Emergency Cleanup, $499.

With WP-CLI, once you have a replacement: wp plugin deactivate xmlrpc-attacks-blocker && wp plugin delete xmlrpc-attacks-blocker

Stored cross-site scripting (XSS) in xmlrpc attacks blocker (1.0 and older)

Affected: 1.0 and older
Fixed in: unknown
Access needed (per CVSS): No login needed; someone on the site has to click a link or open a page

Details from the advisory

The xmlrpc attacks blocker plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.0, via the 'X-Forwarded-For' HTTP header. This is due to the plugin trusting and logging attacker-controlled IP header data and rendering debug log entries without output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views the debug log page.
