This is due to the `create_review_permissions_check()` function comparing the user-supplied `key` parameter against the order's `ivole_secret_key` meta value using strict equality (`===`), without verifying that the stored key is non-empty. For orders where no review reminder email has been sent, the `ivole_secret_key` meta is not set, causing `get_meta()` to return an empty string. An attacker can supply `key: \"\"` to match this empty value and bypass the permission check. This makes it possible for unauthenticated attackers to submit, modify, and inject product reviews on any product — including products not associated with the referenced order — via the REST API endpoint `POST /ivole/v1/review`. Reviews are auto-approved by default since `ivole_enable_moderation` defaults to `\"no\"`.","state":"PUBLISHED","assigner":"Wordfence","published_at":"2026-04-10 02:16:03","updated_at":"2026-04-10
