CVE-2026-35455: immich has Stored XSS via OCR Text in 360° Panorama Viewer

immich is a high performance self-hosted photo and video management solution. Prior to 2.7.0, sStored Cross-Site Scripting (XSS) in the 360° panorama viewer allows any authenticated user to execute arbitrary JavaScript in the browser of any other user who views the malicious panorama with the OCR overlay enabled. The attacker uploads an equirectangular image containing crafted text; OCR extracts it, and the panorama viewer renders it via innerHTML without sanitization. This enables session hijacking (via persistent API key creation), private photo exfiltration, and access to GPS location history and face biometric data. This vulnerability is fixed in 2.7.0.
