CyberRota Analysis
AI-GeneratedMarten versions 7.0.0 to 9.13.0 are vulnerable to SQL injection due to improper handling of attacker-controlled strings in LINQ and tenant-management operations, particularly through dictionary indexer keys and other database interactions. This vulnerability can lead to authorization bypass, blind data exfiltration, and potential data modification if semicolon-batched statements are allowed. Organizations using affected versions should prioritize patching to version 9.13.0 to mitigate these critical risks.

Original NVD Description
Marten is a .NET Transactional Document DB and Event Store on PostgreSQL. From version 7.0.0 until 9.13.0, several Marten LINQ and tenant-management paths interpolate runtime, potentially attacker-controlled strings into single-quoted SQL literals without escaping or parameterization. The primary confirmed vector is a dictionary indexer key used by Where filters in src/Marten/Linq/Members/Dictionaries/DictionaryItemMember.cs. Additional affected sinks include SelectParser.cs, DatabaseScopedTenantPartitions.cs, and DeleteAllForTenant.cs reached through IEventStore.DeleteProjectionProgressAsync, while DictionaryContainsKeyFilter.cs (Newtonsoft serializer only; System.Text.Json is not affected) handles ContainsKey calls. Events/Daemon/Internals/EventLoader.cs contains a related per-tenant partition-pruning literal that the advisory identifies as a defense-in-depth sink. A crafted single quote can escape the generated literal, enabling filter or multi-tenant authorization bypass and blind data exfiltration, and deployments that permit semicolon-batched Npgsql statements may also allow data modification. This issue is fixed in version 9.13.0.
