{"id":"CVE-2026-49833","state":"PUBLISHED","title":"DSpace: Path Traversal possible in LDN message generation","description":"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.","publishedAt":"2026-09-02T17:18:00.856Z","updatedAt":"2026-09-02T17:42:09.238Z","severity":{"score":5.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:L/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["DSpace DSpace"],"affected":[{"vendor":"DSpace","product":"DSpace","versions":[{"version":">= 8.0-rc1, < 8.4","status":"affected"},{"version":">= 9.0-rc1, < 9.3","status":"affected"},{"version":"= 10-rc1","status":"affected"}]}],"references":["https://github.com/DSpace/DSpace/security/advisories/GHSA-9qm4-rh6w-pq5x","https://github.com/DSpace/DSpace/pull/12540","https://github.com/DSpace/DSpace/pull/12552"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/49xxx/CVE-2026-49833.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-49833","state":"PUBLISHED","datePublished":"2026-09-02T17:18:00.856Z","dateUpdated":"2026-09-02T17:42:09.238Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-01T18:50:36.056Z"},"containers":{"cna":{"title":"DSpace: Path Traversal possible in LDN message generation","descriptions":[{"lang":"en","value":"DSpace open source software is a repository application which provides durable access to digital resources.
