Subscriber import data disclosure via unchecked AJAX action
Published Aug 5, 2026 · Updated Aug 5, 2026
Information disclosure in MLSImport before 7.0.4 allows remote authenticated users to read import logs and metadata for arbitrary posts. The mlsimport_logger_per_item AJAX action accepts an arbitrary post_id and returns the shared import log and import-related meta values without nonce or capability checks. Subscriber access is sufficient, but the response contains data only after an import has populated the log and metadata.
