CVE-2026-12426Network attack vector

Unauthenticated protected-content inference via REST pagination

Published Jul 11, 2026 · Updated Jul 11, 2026

Sensitive information exposure in Caseproof Members 3.2.22 and earlier allows remote attackers to infer protected post content via REST requests. members_filter_protected_posts_for_rest removes protected posts after WordPress computes REST totals, leaving counts and pagination headers dependent on hidden matches. Content Permissions and REST hiding must apply to restricted posts; repeated keyword and page-size probes disclose existence and counts, not full post bodies.
