Upgrade Marten to version 9.13.0 or higher.
Overview
Affected versions of this package are vulnerable to SQL Injection via unescaped string literals in DictionaryItemMember, DictionaryContainsKeyFilter, SelectParser, DeleteAllForTenant, DatabaseScopedTenantPartitions, and EventLoader. An attacker can inject arbitrary SQL, bypass tenant or row filters, and exfiltrate data by supplying a value containing a single quote in a dictionary indexer key, ContainsKey argument, projected constant, or tenant id used in partitioning or teardown SQL.
Workarounds
- Do not pass untrusted input as a dictionary indexer key,
ContainsKeyargument, orSelectconstant. - Do not pass untrusted input as a tenant id into projection teardown or tenant partition provisioning.
- Disable multi-statement command batching to limit the blast radius if SQL injection is triggered.
