Envira Gallery Lite < 1.16.2 Missing Authorization via Gallery Conversion REST Endpoint

Published Oct 9, 2026 CVSS 4.0 · 5.3 Medium EPSS < 1% KEV · Not listed
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.
