{"id":"CVE-2026-49833","aliases":["GHSA-9qm4-rh6w-pq5x"],"url":"https://o3.security/vulnerability/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.","published":"2026-09-02T17:18:00.856Z","modified":"2026-09-11T03:30:43.268696500Z","cvss":{"score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:L/A:L"},"epss":{"score":0.00267,"percentile":0.1902,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.dspace:dspace-api","fixedVersion":"8.4"},{"ecosystem":"Maven","name":"org.dspace:dspace-api","fixedVersion":"9.3"},{"ecosystem":"Maven","name":"org.dspace:dspace-api","fixedVersion":"10.0"}],"fix":{"url":"https://github.com/DSpace/DSpace/pull/12540","label":"DSpace/DSpace#12540"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-11T03:30:43.268696500Z"}}
