CVE-2026-104079: Missing Authorization in Syed Balkhi Envira Gallery
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.

Technical Analysis
CVE-2026-104079 describes a missing authorization vulnerability in Envira Gallery Lite prior to version 1.16.2. The vulnerability exists in the gallery conversion REST endpoint, which improperly authorizes users by only checking edit permissions on the source post and using a hard-coded publish status. This allows lower-privileged authenticated users to create and publish galleries without the required capabilities. Furthermore, the endpoint accepts arbitrary image IDs without verifying ownership, permitting attackers to publish unauthorized attachments.
Potential Impact
An attacker with lower-level authenticated access can create and publish galleries without proper authorization, potentially leading to unauthorized content publication. This could result in content integrity issues and unauthorized exposure of attachments that the attacker does not own.
Mitigation Recommendations
A fixed version 1.16.2 of Envira Gallery Lite is available that addresses this missing authorization vulnerability. Users should upgrade to version 1.16.2 or later to remediate this issue.
