CVE-2026-3460: REST API TO MiniProgram <= 5.1.2 - Authenticated (Subscriber+) Insecure Direct Object Reference via 'userid' REST API Parameter

The REST API TO MiniProgram plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.1.2. This is due to the permission callback (update_user_wechatshop_info_permissions_check) only validating that the supplied 'openid' parameter corresponds to an existing WordPress user, while the callback function (update_user_wechatshop_info) uses a separate, attacker-controlled 'userid' parameter to determine which user's metadata gets modified, with no verification that the 'openid' and 'userid' belong to the same user. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify arbitrary users' store-related metadata (storeinfo, storeappid, storename) via the 'userid' REST API parameter.

Security readout for executives and security teams

Plain-English summary

CVE-2026-3460 affects the WordPress plugin REST API TO MiniProgram through version 5.1.2. A logged-in low-privilege user may be able to change store-related metadata for other users. This is an integrity issue, not a data theft or full site takeover finding based on the provided sources.

Executive priority

Treat as a medium-priority integrity risk. Prioritize internet-facing WordPress sites where customers, partners, or unknown users can create accounts. Remediate during the next security maintenance cycle unless the plugin supports critical commerce or store workflows.

Technical view

The plugin’s REST permission check validates that an 'openid' maps to an existing WordPress user, but the update handler uses a separate attacker-controlled 'userid' to select whose metadata is modified. Sources identify affected metadata as storeinfo, storeappid, and storename. The issue is described as authenticated Subscriber+ IDOR.

Likely exposure

Exposure is limited to WordPress sites running REST API TO MiniProgram version 5.1.2 or earlier, especially sites allowing untrusted users to authenticate as Subscribers or higher. Sites without this plugin are not affected.

Exploitation context

The source bundle does not show CISA KEV listing or confirmed active exploitation. Exploitation requires an authenticated user according to the description, despite the bundled CVSS vector showing PR:N, which appears inconsistent with the narrative.

Researcher notes

The key control failure is object binding: authorization validates one user identifier but the state change targets another. Code references in WordPress Trac are provided for the permission callback and update path. Fix availability is not established in the provided sources.

Mitigation direction

  • Inventory WordPress sites for REST API TO MiniProgram installations.
  • Identify plugin versions at or below 5.1.2.
  • Check vendor or WordPress plugin guidance for a fixed release.
  • Update if a fixed version is available from trusted sources.
  • Disable the plugin if unused or no fix is available.
  • Review whether public user registration is necessary.

Validation and detection

  • Confirm whether the plugin is installed on each WordPress site.
  • Record the installed plugin version.
  • Review user roles for untrusted Subscriber-level accounts.
  • Inspect store-related user metadata for unexpected changes.
  • Monitor relevant WordPress REST activity for suspicious authenticated updates.
