Vulnerability in 4TUResearchData djehuty

- Public proof-of-concept exploit exists (CISA SSVC)
[ Description ]Official description
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.
