CVE-2026-54833Network attack vector

Unauthenticated privileged REST access via hardcoded credential

Published Jun 26, 2026 · Updated Jun 26, 2026

Authentication bypass in Dev Kabir Enable CORS 2.0.3 and earlier allows remote attackers to access privileged REST endpoints. The permissions_check method in src/Traits/Api.php passes the Authorization header to password_verify against a fixed bcrypt hash and treats a match as authorized. A matching header value is required; successful requests bypass the manage_options capability check and permit reading or changing plugin settings.
