CVE-2026-53662

Description

immich is a high performance self-hosted photo and video management solution. From commit 4ffa26c9 until 4eb1003, a reflected cross-site scripting (XSS) vulnerability on the /auth/login page allows an attacker to fully compromise any authenticated user-s account with a single link click. The continue query parameter is read from the URL and passed to SvelteKit-s redirect() without any scheme or origin validation, allowing attacker-controlled JavaScript to execute inside Immich-s origin. The payload then uses the victim-s existing session to mint an all-permission API key on their account, leading to persistent account takeover. This vulnerability is fixed in commit 4eb1003.
