Database compromise via numeric JSON filter keys
Published Jan 28, 2026 · Updated Jan 28, 2026
SQL injection in EGroupware releases before 23.1.20260113 and 26.0.20260113 allows remote authenticated users to control database queries. Numeric JSON col_filter keys become integers during decoding, so Db::column_data_implode and Storage\Base::parse_search append attacker values directly to SQL WHERE clauses. A low-privileged account and access to a Nextmatch-backed view are sufficient; the resulting queries can read, modify, or delete application data.
