CVE-2026-35455 immich-app CVE debrief

CVE-2026-35455 is a Stored Cross-Site Scripting (XSS) vulnerability in the 360° panorama viewer of Immich, a self-hosted photo and video management solution. Prior to version 2.7.0, an authenticated user can upload an equirectangular image with crafted text, which is extracted by OCR and rendered via innerHTML without sanitization. This allows the execution of arbitrary JavaScript in the browser of any other user who views the malicious panorama with the OCR overlay enabled, potentially leading to session hijacking, private photo exfiltration, and access to sensitive data such as GPS location history and face biometric data.

Who should care

Users of Immich version 2.6.0 or earlier should be aware of this vulnerability and take immediate action to upgrade to version 2.7.0 or apply compensating controls. This includes operators, platform administrators, vulnerability management teams, and security teams who need to assess and mitigate this vulnerability.

Technical summary

The vulnerability exists in the 360° panorama viewer of Immich, where an attacker can upload a malicious equirectangular image containing crafted text. When another user views the panorama with the OCR overlay enabled, the crafted text is extracted by OCR and rendered via innerHTML without proper sanitization, allowing for the execution of arbitrary JavaScript. This can lead to session hijacking, private photo exfiltration, and access to sensitive data such as GPS location history and face biometric data.

Defensive priority

High

Recommended defensive actions

  • Upgrade Immich to version 2.7.0 or later
  • Implement compensating controls such as input validation and output encoding
  • Monitor for suspicious activity and implement logging and incident response plans
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
