Repository metadata tampering via unescaped session names

Published Oct 1, 2026 · Updated Oct 1, 2026

SPARQL injection in 4TU.ResearchData Djehuty before 26.3.2 allows remote authenticated users to alter repository metadata via session editing. The session-update template inserts the name into a DELETE/INSERT query as a safe string, while validation preserves quotes that let the name escape its string literal. A logged-in depositor can write or delete triples in the RDF store shared by all accounts and datasets.
