From versions 8.0-rc1 to before 8.4, 9.0-rc1 to before 9.3, and 10-rc1 to before 10.0, a path traversal vulnerability is possible via the COAR Notify / LDN service in DSpace. The attacker MUST already have DSpace administrator credentials in order to perform the attack. When reading a file input stream of an \"inbound pattern\" / \"template\", used to generate an LDN message, the LDN class does not check for path traversal or restrict the templates to a known base path. This could allow an untrusted file from elsewhere in the file system (e.g. an export log, a bitstream path, a temporary file) to be read and interpreted as an Apache Velocity template. This issue has been patched in versions 8.4, 9.3, and 10.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-49833)\n\nAffected packages:\n\n- `org.dspace:dspace-api >= 8.0-rc1, <= 8.3`\n- `org.dspace:dspace-api >= 9.0-rc1, <= 9.2`\n- `org.dspace:dspace-api = 10.0-rc1`\n\nPatched in:\n\n- `org.dspace:dspace-api 8.4`\n- `org.dspace:dspace-api 9.3`\n- `org.dspace:dspace-api 10.0`\n\nSource: https://github.com/advisories/GHSA-9qm4-rh6w-pq5x","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
