Path Traversal in DSpace Curation Task

Publication date: 2026-09-02

Last updated on: 2026-09-02

Assigner: GitHub, Inc.

Description
DSpace open source software is a repository application which provides durable access to digital resources. Prior to versions 7.6.7, 8.4, 9.3, and 10.0, the Curation Task feature allows an output path to be used by the reporter (-r parameter), typically used to stream results and status of curation task operations. It is not restricted to any particular base path, meaning that any path writable by the DSpace (often 'tomcat') user is allowed. This constitutes a Path Traversal Vulnerability in the curate script. This issue has been patched in versions 7.6.7, 8.4, 9.3, and 10.0.

Executive Summary

This is a Path Traversal vulnerability in DSpace's Curation Task feature. It allows attackers with administrative access to manipulate file paths via the reporter output path parameter (-r), potentially writing files to unintended locations. The issue exists because the output path is not restricted to a base directory.

Detection Guidance

To detect this vulnerability, check the DSpace version installed on your system. Run commands like 'dspace version' or check the version in the DSpace configuration files. If your version is 7.6.6 or earlier, 8.0 to 8.3, or 9.0 to 9.2, the system is vulnerable.

Impact Analysis

An attacker could overwrite critical files like configuration or binaries, leading to denial of service or privilege escalation. This could disrupt repository operations or allow unauthorized system access if combined with other vulnerabilities.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by allowing unauthorized file writes to sensitive locations. Attackers with admin access could overwrite critical files like configurations or binaries, leading to data breaches or system compromise. Such breaches may violate GDPR's data protection requirements or HIPAA's safeguards for protected health information.

Mitigation Strategies

Immediately upgrade to DSpace versions 7.6.7, 8.4, 9.3, or 10.0. If upgrading is not possible, manually apply the patches provided in the security advisory or temporarily disable curation tasks as a workaround.
