{"cve":"CVE-2026-49833","nvd":{"published":"2026-09-02T18:19:32.980","modified":"2026-09-09T21:05:23.237","status":"Awaiting Analysis","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:L/A:L","score":5.5},"cwes":["CWE-22"],"references":["https://github.com/DSpace/DSpace/pull/12540","https://github.com/DSpace/DSpace/pull/12552","https://github.com/DSpace/DSpace/security/advisories/GHSA-9qm4-rh6w-pq5x"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:50:50.842544443+00:00"},"epss":{"cve":"CVE-2026-49833","score":0.0037,"percentile":0.30989,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-9qm4-rh6w-pq5x","url":"https://osv.dev/vulnerability/GHSA-9qm4-rh6w-pq5x","summary":"DSpace: Path Traversal is possible through LDN message generation","modified":"2026-07-08T20:56:35.590014Z","packages":[{"ecosystem":"Maven","name":"org.dspace:dspace-api","purl":"pkg:maven/org.dspace/dspace-api","ranges":[">=8.0-rc1 <8.4"],"fixed":["8.4"]},{"ecosystem":"Maven","name":"org.dspace:dspace-api","purl":"pkg:maven/org.dspace/dspace-api","ranges":[">=9.0-rc1 <9.3"],"fixed":["9.3"]},{"ecosystem":"Maven","name":"org.dspace:dspace-api","purl":"pkg:maven/org.dspace/dspace-api","ranges":[">=10.0-rc1 <10.0"],"fixed":["10.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
