Subject: [PATCH] Prevent Java deserialization of internal classes (#1991)
|
||||
|
||||
Adversaries might be able to forge data which can be abused for DoS attacks.
|
||||
These classes are already writing a replacement JDK object during serialization for a long time, so this change should not cause any issues.
