Authenticated arbitrary method calls via reflex dispatch
Published Mar 12, 2024 · Updated Feb 13, 2025
Unsafe reflection in StimulusReflex before 3.4.2 and 3.5.0.rc1 through 3.5.0.rc3 allows remote authenticated users to call unintended methods. The WebSocket target field supplies both a Reflex subclass and method name, and dispatch accepts inherited public methods not declared as reflex actions. A valid application session can therefore overwrite trusted instance state; prerelease builds also expose render_collection for arbitrary code execution.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <3.4.2
- Affected versionversion=< 3.4.2
- Affected versionversion=>= 3.5.0.rc1, < 3.5.0.rc4
- Affected versionversion=3.5.0.rc1 <3.5.0.rc4
