CVE-2026-67287Network attack vector

Unauthenticated comment insertion via guest-setting override

Published Aug 12, 2026 · Updated Aug 12, 2026

Improper access control in JoomShaper SP Page Builder 1.0.0 through 6.7.1 allows remote attackers to create unauthorized comments. The Comment addon trusts user-supplied input that overrides the disabled Allow Anonymous Comments setting instead of enforcing it. No authentication is required, but the affected page must use the Comment addon with anonymous comments disabled; exploitation inserts site content without changing other configuration.
