Authenticated metadata disclosure via unrestricted REST field lookup
Published Aug 10, 2026 · Updated Aug 10, 2026
Authorization bypass in CubeWP Framework through 1.1.30 allows remote authenticated users to read arbitrary post and user metadata via its REST API. The cubewp-custom-fields/v1/render route accepts an object ID and arbitrary metadata key without checking per-object read permission or restricting the key to registered CubeWP fields. Contributor-level access and a standard WordPress REST nonce are sufficient to read metadata from other users’ nonpublic posts and administrator accounts.
