Exploitation Conditions

Remote unauthenticated attacker can exploit SQL injection in the MRI feedback popup window of LORIS imaging browser versions prior to 27.0.3 and 28.0.1. No user interaction required. Affects self-hosted LORIS installations with default configurations.

Impact

Network-accessible SQL injection in unauthenticated MRI feedback popup enables direct database read access without user interaction. CVSS 7.5 reflects confidentiality impact on sensitive neuroimaging data. Priority depends on deployment scope-self-hosted academic systems may have limited external exposure, reducing blast radius versus public instances.

Exploit ScenarioDerived

Attacker crafts malicious SQL payload in MRI feedback popup parameters via HTTP GET/POST. No authentication required; payload executes directly against database, exfiltrating patient neuroimaging records or project metadata in single request.

AnalysisAIv1 – Apr 08, 2026

SQL injection in LORIS neuroimaging research platform versions prior to 27.0.3 and 28.0.1 enables unauthenticated remote attackers to extract or modify database contents via the MRI feedback popup window in the imaging browser module. The vulnerability permits unauthorized access to sensitive neuroimaging research data and project management information without authentication. CVSS 7.5 (High severity) reflects network-accessible attack vector with low complexity. No public exploit identified at time of analysis.

RemediationAI

Vendor-released patch: upgrade to LORIS version 27.0.3 (for 27.x deployments) or 28.0.1 (for 28.x deployments). These releases implement parameterized queries and input validation to prevent SQL injection in the MRI feedback popup. No workarounds exist; upgrade is mandatory. Installations using affected versions should audit database access logs for suspicious query patterns prior to patching. Consult official security advisory for upgrade procedures: https://github.com/aces/Loris/security/advisories/GHSA-9r29-6jgc-3ggh. Post-upgrade, verify imaging browser MRI feedback functionality operates normally without SQL injection risk.

Technical ContextAI · show details

Unsafe SQL query construction in MRI feedback popup code allows direct database query manipulation. CWE-89 SQL injection stems from inadequate input sanitization in imaging browser's feedback window handler. Attack requires no authentication (PR:N) and exploits LORIS's web application tier to bypass database access controls.

DescriptionCVE.org

LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. Prior to 27.0.3 and 28.0.1, a SQL injection has been identified in some code sections for the MRI feedback popup window of the imaging browser. Attackers can use SQL ingestion to access/alter data on the server. This vulnerability is fixed in 27.0.3 and 28.0.1.

Executive ViewAI

Why It Matters

LORIS neuroimaging research platform versions prior to 27.0.3 and 28.0.1 contain an unauthenticated SQL injection vulnerability in the imaging browser module that allows remote attackers to extract or modify sensitive research data and project information without credentials. Organizations deploying LORIS for clinical or research neuroimaging studies face immediate risk of data breach and research integrity compromise affecting patient privacy and regulatory compliance.

Business Impact: High
Compensating Controls

Apply vendor patch. If immediate patching is not feasible, restrict network access to LORIS imaging browser module to authenticated VPN or internal networks only; disable or restrict the MRI feedback popup functionality until patch is applied; implement WAF rules to block common SQL injection payloads targeting the imaging browser module; enable database query logging and set alerts for anomalous SELECT/UPDATE/DELETE activity.
