CVE-2026-104867 · Severity: medium · CVSS 4.3 · Published 2026-11-05

Immich is a self-hosted photo and video management application. A vulnerability in versions 3.0.0 through 3.2.0 allows any authenticated user to view another user's activity patterns, including when photos were uploaded or taken, without proper authorization. While the vulnerability only exposes activity counts and dates rather than the photos themselves, it reveals when and how much users are uploading content.

## How to fix

- Fixed in 3.2.0

## Technical details

The GET /api/admin/users/{id}/calendar-heatmap endpoint uses only basic Permission.UserRead instead of admin-route enforcement, and UserAdminService does not verify that the authenticated user matches the requested user ID. An authenticated non-admin attacker can enumerate other users' upload/capture activity heatmaps across arbitrary date ranges. The returned data includes counts of archived and locked assets per day but not asset metadata or content, making this a confidentiality issue only.
