Technical description
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.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
