CVE-2026-88931Network attack vector

Unauthenticated settings overwrite via unrestricted option writes

Published Oct 9, 2026 · Updated Oct 9, 2026

Settings overwrite in Social Web Suite 4.1.12 and earlier allows remote attackers to change plugin options via an unauthenticated endpoint. The endpoint does not restrict writable settings, including the shared secret guarding privileged plugin endpoints; the supplied record does not identify its path or handler. No WordPress account is required, and the stated impact concerns plugin settings and their shared-secret gate, not arbitrary WordPress-wide options.
