Envira Gallery Lite before 1.16.2 contains a missing authorization vulnerability in its gallery conversion REST endpoint that allows lower-privileged authenticated users to create and publish Envira galleries without the required capabilities, because the endpoint only checks edit permissions on the source post and uses a hard-coded publish status. Attackers can also supply arbitrary caller-controlled image IDs without ownership verification to publish unauthorized content using attachments they are not authorized to use.
