CVE-2026-86706: Quick Quotes plugin lets anyone change site settings
CVE-2026-86706 · published 2 days ago
Summary
The Quick Quotes add‑on for WordPress up to version 1.0.0 lets anyone on the internet send a special request that changes the plugin’s configuration. Because the request isn’t checked for permission, an unauthenticated user could modify important site options and potentially cause the site to stop working. Update the plugin to a newer version or remove it until the vendor releases a fix.
