CVE-2026-86706Network attack vector

Unauthenticated settings alteration via unchecked AJAX option writes

Published Oct 11, 2026 · Updated Oct 11, 2026

Unchecked AJAX writes in Quick quotes – WPSHARE247 1.0.0 and earlier allow remote attackers to alter site settings. An AJAX action accepts a caller-selected option to write without checking capabilities or a nonce; the supplied advisory does not name the handler. No authentication is required, and altered settings can make the WordPress site unavailable; the specific outage behavior is not documented.
