{"id":"CVE-2026-49833","summary":"DSpace: Path Traversal possible in LDN message generation","details":"DSpace open source software is a repository application which provides durable access to digital resources. 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.","aliases":["GHSA-9qm4-rh6w-pq5x"],"modified":"2026-09-04T03:46:24.154514247Z","published":"2026-09-02T17:18:00.856Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49833.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"= 10-rc1"},{"last_affected":"= 10-rc1"}]}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49833.json"},{"type":"ADVISORY","url":"https://github.com/DSpace/DSpace/security/advisories/GHSA-9qm4-rh6w-pq5x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49833"},{"type":"FIX","url":"https://github.com/DSpace/DSpace/pull/12540"},{"type":"FIX","url":"https://github.com/DSpace/DSpace/pull/12552"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dspace/dspace","events":[{"introduced":"769129115a4e2f987b01e9af5f3191d10fb1ecc0"},{"fixed":"544632c10883df7d149e68c8accb68c135c083e1"},{"introduced":"0896000a6539395c0e3d19a7187b58f39a72a172"},{"fixed":"e0fae432fff2743da99e3f9152e9439d549652e7"}],"database_specific":{"extracted_events":[{"introduced":"8.0-rc1"},{"fixed":"8.4"},{"introduced":"9.0-rc1"},{"fixed":"9.3"}],"source":"AFFECTED_FIELD"}}],"versions":["dspace-9.0","dspace-8.3","dspace-9.2","dspace-8.2","dspace-9.1","dspace-9.0-rc1","dspace-8.1","dspace-8.0","dspace-8.0-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-49833.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:L/A:L"}]}
