An issue in Clojure versions 1.20 to 1.12.0-alpha5 allows an attacker to cause a denial of service (DoS) via the clojure.core$partial$fn__5920 function.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Potential Mitigations
- Make fields transient to protect them from deserialization.
- An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
