CVE-2026-49833Network attack vector

Administrator file disclosure via unrestricted LDN template paths

Published Sep 2, 2026 · Updated Sep 2, 2026

Path traversal in DSpace 8.0-rc1 through 8.3, 9.0-rc1 through 9.2, and 10.0-rc1 allows remote authenticated users to read local files. The LDN class opens an administrator-supplied inbound template path without canonicalizing it or confining it to $dspace.dir/config/ldn, then interprets the file as Apache Velocity. DSpace administrator access and an enabled LDN service are required; crafted templates expose server-readable data and can contribute to a separate code-execution chain.
