CVE-2026-81767Network attack vectorHinoki check available

Unauthenticated protected-state modification via missing authorization

Published Aug 28, 2026 · Updated Aug 28, 2026

Missing authorization in Ido Kobelkowsky Simple Payment 2.5.2 and earlier allows remote attackers to invoke a protected action. Patchstack and upstream materials do not disclose the endpoint, function, authorization omission, or specific action involved. The action is network-reachable without an account or user interaction, and the published assessment limits the consequence to unauthorized modification.
