CVE-2026-49830

Status: Awaiting AnalysisMedium (4.4)—

DSpace open source software is a repository application which provides durable access to digital resources. Prior to versions 7.6.7, 8.4, 9.3, and 10.0, when ingesting an aggregated ORE resource by URI (using the OAI-ORE Harvester), the ORE Ingestion Crosswalk does not validate the URI scheme. This may allow for local file inclusion via malicious paths like file:///etc/passwd. The attacker MUST already have DSpace collection administrator privileges in order to perform the attack. This issue has been patched in versions 7.6.7, 8.4, 9.3, and 10.0.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
