Summary

The Sifalo Pay WordPress plugin, from 2.0 before 2.5.3, does not verify ownership of or authorisation for the order it updates when it handles a payment return (CWE-862, Missing Authorization). An unauthenticated attacker can write arbitrary payment session metadata to any order in the store and force any order awaiting payment into a failed state. The CVSS 3.1 base score is 5.3 (MEDIUM), and CISA's KEV catalog does not list the issue.
