MITRE ATT&CK

2 techniques across 2 tactics: Initial Access, Execution

The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up.

Exploitation Conditions

Requires authenticated user access to Immich versions prior to 2.7.0. Attacker uploads malicious equirectangular image; victim must view panorama with OCR overlay enabled in 360° panorama viewer. Victim interaction required: opening the panorama view.

Impact

Authenticated stored XSS in panorama OCR overlay enables session hijacking, private photo/GPS exfiltration, and biometric data access. High impact (C:H, I:H, A:H) but requires local attack vector and user interaction to trigger viewing. CVSS 7.3 reflects moderate urgency; self-hosted deployments with shared panorama collections face greatest risk.

Exploit ScenarioDerived

Attacker uploads equirectangular image with OCR-extractable malicious text; victim views panorama with OCR overlay enabled, triggering unsanitized innerHTML rendering. JavaScript executes in victim's session, creating persistent API key for account takeover and data exfiltration.

AnalysisAIv1 – Apr 08, 2026

Stored Cross-Site Scripting in Immich photo management platform versions prior to 2.7.0 enables authenticated attackers to execute arbitrary JavaScript when victims view malicious 360° panorama images with OCR overlay enabled. Attackers upload specially crafted equirectangular images containing malicious text that OCR extracts and the panorama viewer renders unsanitized via innerHTML. Exploitation permits session hijacking through persistent API key creation, exfiltration of private photos, GPS location history theft, and unauthorized access to facial biometric data. No public exploit identified at time of analysis.

RemediationAI

Vendor-released patch: Immich 2.7.0 resolves this vulnerability through input sanitization in the panorama viewer OCR rendering pathway. Organizations should immediately upgrade all Immich instances to version 2.7.0 or later. As an interim workaround, disable OCR overlay functionality in the panorama viewer interface or restrict panorama upload permissions to trusted administrators only until patching is complete. Review API keys created during the vulnerability window for unauthorized persistent access tokens. Full vendor advisory available at https://github.com/immich-app/immich/security/advisories/GHSA-9qx4-67jm-cc66 with additional technical details and remediation guidance.

Technical ContextAI · show details

Root cause is improper neutralization of input (CWE-79) in panorama viewer's OCR text rendering path. OCR engine extracts text from uploaded equirectangular images, which is subsequently inserted into DOM via innerHTML without sanitization, allowing JavaScript execution in victim browsers accessing affected panoramas with OCR overlay active.

DescriptionNVD

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.

Executive ViewAI

Why It Matters

Immich photo management platform versions before 2.7.0 contain a stored cross-site scripting vulnerability that allows authenticated users to inject malicious code through 360° panorama images with OCR enabled, potentially compromising session tokens, private photo libraries, location history, and facial recognition data of other users who view the malicious content. Organizations using Immich should prioritize immediate patching, as the attack requires only standard user authentication but impacts all users accessing shared photo galleries.

Business Impact: High
Compensating Controls

Vendor-released patch: Immich 2.7.0 or later. If immediate patching is not feasible, disable OCR and panorama viewer features in Immich configuration as interim mitigation; restrict photo library sharing to essential users only; implement network segmentation to limit Immich user base; monitor for suspicious API key creation events.
