Authenticated data disclosure via unrestricted dynamic expressions
Published Jan 21, 2025 · Updated Feb 4, 2025
Information disclosure in System.Linq.Dynamic.Core before 1.6.0 allows remote authenticated users to read application data via dynamic queries. The expression parser permits user-supplied projections to traverse reflection metadata and resolve exposed static properties or fields instead of restricting accessible types. Reachability requires an application to pass attacker-controlled expressions into the library; exposed data can include installed package versions and application settings.
