CyberRota Analysis
AI-GeneratedThe vulnerability allows unauthenticated attackers to exploit keyset pagination in the Ash framework, enabling them to inject malicious filter expressions that can lead to SQL injection or arbitrary code execution. This issue arises from the improper handling of deserialized data, which bypasses necessary security checks, allowing crafted inputs to be executed within the application context. Organizations using affected versions of the Ash framework (from 1.17.0 to before 3.31.3) should prioritize remediation to mitigate potential exploitation risks.

Original NVD Description
Deserialization of Untrusted Data vulnerability in ash-project ash allows an unauthenticated attacker to inject a filter expression through a forged keyset pagination cursor, resulting in SQL injection or code execution depending on the data layer. Read actions with keyset pagination decode the client-supplied page[:after] or page[:before] cursor in decode_values/2 in lib/ash/page/keyset.ex using non_executable_binary_to_term/2 with [:safe]. That guard blocks new atoms, funs, and ports, but not a struct built from atoms already interned in a running Ash application, so a decoded %Ash.Query.Call{} expression survives and is spliced into the keyset filter as a comparison value in do_filters/4 and evaluated. Because the cursor bypasses the Ash.Expr macro, the runtime never applies the private?/public? gate that would otherwise reject it. On AshPostgres the injected fragment is inlined into the SQL query; on the ETS and Simple data layers it is evaluated in-process as an arbitrary function call. This issue affects ash: from 1.17.0 before 3.31.3.
