What is CVE-2026-73975?

The djehuty research data repository system allows authenticated depositors to inject arbitrary SPARQL code into state-modifying queries by crafting a specific session name. This vulnerability leads to unauthorized writing and deletion of metadata across the shared RDF store, impacting all accounts and datasets within the repository. Affected users are those with logged-in accounts, and because djehuty supports self-registration via ORCID/SAML, the access barrier is low. This issue has been addressed in version 26.3.2.

Affected Version(s)

djehuty < 26.3.2
