An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-49833 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.dspace:dspace-api (Maven): affected from 10.0-rc1; fixed in 10.0\n- org.dspace:dspace-api (Maven): affected from 10.0-rc1; fixed in 10.0\n- org.dspace:dspace-api (Maven): affected from 8.0-rc1; fixed in 8.4\n- org.dspace:dspace-api (Maven): affected from 8.0-rc1; fixed in 8.4\n- org.dspace:dspace-api (Maven): affected from 9.0-rc1; fixed in 9.3\n- org.dspace:dspace-api (Maven): affected from 9.0-rc1; fixed in 9.3\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-49833/ (Markdown: https://insights.sbomify.com/CVE-2026-49833/index.md)","id":"CVE-2026-49833","markdown":"https://insights.sbomify.com/CVE-2026-49833/index.md","name":"CVE-2026-49833","record":{"aliases":["GHSA-9qm4-rh6w-pq5x"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_read","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"DSpace repository application","requires_auth":"high_privilege","summary":"An authenticated DSpace administrator can exploit path traversal in LDN message generation to read arbitrary files and potentially execute code via template injection.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"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.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"DSpace: Path Traversal possible in LDN message generation","id":"CVE-2026-49833","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":6,"n_references":3,"next":{"headline":"sigstore-go: Multi-log threshold bypass via single compromised log","id":"CVE-2026-49834"},"packages":[{"ecosystem":"Maven","fixed":["10.0"],"introduced":["10.0-rc1"],"last_affected":[],"package":"org.dspace:dspace-api","purl":null,"source":"GHSA-9qm4-rh6w-pq5x"},{"ecosystem":"Maven","fixed":["10.0"],"introduced":["10.0-rc1"],"last_affected":[],"package":"org.dspace:dspace-api","purl":"pkg:maven/org.dspace/dspace-api","source":"GHSA-9qm4-rh6w-pq5x"},{"ecosystem":"Maven","fixed":["8.4"],"introduced":["8.0-rc1"],"last_affected":[],"package":"org.dspace:dspace-api","purl":null,"source":"GHSA-9qm4-rh6w-pq5x"},{"ecosystem":"Maven","fixed":["8.4"],"introduced":["8.0-rc1"],"last_affected":[],"package":"org.dspace:dspace-api","purl":"pkg:maven/org.dspace/dspace-api","source":"GHSA-9qm4-rh6w-pq5x"},{"ecosystem":"Maven","fixed":["9.3"],"introduced":["9.0-rc1"],"last_affected":[],"package":"org.dspace:dspace-api","purl":null,"source":"GHSA-9qm4-rh6w-pq5x"},{"ecosystem":"Maven","fixed":["9.3"],"introduced":["9.0-rc1"],"last_affected":[],"package":"org.dspace:dspace-api","purl":"pkg:maven/org.dspace/dspace-api","source":"GHSA-9qm4-rh6w-pq5x"}],"prev":{"headline":"DSpace: Remote Code Execution (RCE) possible in Velocity Templates used by LDN","id":"CVE-2026-49832"},"products":["DSpace"],"published":"2026-09-02","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-02","vendors":["DSpace"]},"summary":"An authenticated DSpace administrator can exploit path traversal in LDN message generation to read arbitrary files and potentially execute code via template injection.","url":"https://insights.sbomify.com/CVE-2026-49833/"}
