CVE-2026-9591Network attack vector

Administrator news modification via missing antiforgery validation

Published Jun 17, 2026 · Updated Jun 17, 2026

Cross-site request forgery in SimplCommerce before 6233d73e allows remote attackers to alter news items via a crafted form. NewsItemApiController accepted state-changing /api/news-items requests authenticated by an administrator's application cookie without validating an antiforgery token because the global CookieOnlyAutoValidateAntiforgeryTokenAuthorizationFilter was disabled. Exploitation requires an authenticated administrator to submit the form, and the demonstrated consequence is unauthorized news-item creation or modification.
