Authenticated user metadata modification via mismatched identifiers
Published Mar 21, 2026 · Updated Mar 21, 2026
IDOR in REST API TO MiniProgram 5.1.2 and earlier allows remote authenticated users to modify arbitrary users' store metadata. The update_user_wechatshop_info_permissions_check callback validates openid, but update_user_wechatshop_info selects the target account from a separate unchecked userid value. Subscriber-level access is sufficient to overwrite storeinfo, storeappid, and storename metadata for any user.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
