Executive Summary

CVE-2026-49832 is a Remote Code Execution (RCE) vulnerability in DSpace versions 8.0-rc1 to 8.3, 9.0-rc1 to 9.2, and 10-rc1. It exists in Velocity Templates used for COAR Notify/LDN messages. An attacker with admin credentials can exploit this via reflection combined with path traversal to execute arbitrary Java code. The flaw allows full system compromise but requires high privileges.

Detection Guidance

Detecting this vulnerability requires checking DSpace versions and configuration. Verify if your DSpace version is between 8.0-rc1 to 8.3, 9.0-rc1 to 9.2, or 10-rc1. Check dspace.cfg for LDN settings (ldn.enabled=true). Inspect Velocity template files for COAR Notify/LDN messages for suspicious code injection patterns.

Impact Analysis

If exploited, this vulnerability enables attackers to execute arbitrary code on the affected DSpace server, leading to full system compromise. This could result in unauthorized data access, modification, or deletion, disruption of services, and potential lateral movement within the network. The impact is severe but requires administrative access to exploit.

Compliance Impact

This vulnerability could lead to unauthorized access or modification of sensitive data, violating GDPR's integrity and confidentiality principles or HIPAA's security requirements. Organizations using vulnerable DSpace versions may face compliance violations, data breaches, and potential regulatory penalties if exploited.

Mitigation Strategies

Immediately disable LDN by setting ldn.enabled=false in dspace.cfg. Upgrade to patched versions: DSpace 8.4, 9.3, or 10.0. If upgrading is not possible, apply manual patches from PR #12548 (9.x) or #12549 (8.x). Restrict DSpace administrator credentials to trusted users only.
