Title
djehuty: Unauthenticated SPARQL injection in the search API (`order`, `operator`, `key`)
Summary
djehuty is a research data repository system developed by 4TU.ResearchData. Prior to version 26.3.2, An unauthenticated attacker can inject SPARQL into the search/listing queries through three separate parameters. Because the affected queries are read (SELECT) queries, this does not write to the store, but it allows: Cross-graph data exfiltration — e.g. UNION-ing in triples from graphs the request was never scoped to (drafts/private/internal data held in the RDF store); denial of service — expensive or malformed queries that tie up the SPARQL backend / web workers. No account or user interaction is required. This issue has been patched in version 26.3.2.

Title
djehuty: Authenticated SPARQL injection in session editing allows writing arbitrary RDF triples
Summary
djehuty is a research data repository system developed by 4TU.ResearchData. Prior to version 26.3.2, an authenticated depositor can inject arbitrary SPARQL into a state-modifying (DELETE/INSERT) query by supplying a crafted session name, letting them write (and delete) arbitrary triples anywhere in the RDF store. Because the RDF store is shared across all accounts and datasets, this is an integrity compromise of the whole repository's metadata, not just the attacker's own records. Having a logged-in account is a precondition. djehuty allows self-registration via ORCID/SAML, so this is a low barrier in typical deployments. This issue has been patched in version 26.3.2.
