Authenticated object access via user-controlled keys
Published Dec 20, 2023 · Updated Apr 28, 2026
Authorization bypass in Editorial Calendar 3.7.12 and earlier allows remote authenticated users to access objects through user-controlled keys. The CNA and vendor advisory do not identify the affected handler, object type, or operation that accepts the attacker-supplied key without an ownership check. Contributor-level WordPress access is required; the public record reports unauthorized object access but does not establish a specific disclosure, modification, or service interruption.
