+# v3.0.1
+
+Fixed:
+ - Security issue: an attacker specifying a large "p2c" value can cause
+ JSONWebEncryption.Decrypt and JSONWebEncryption.DecryptMulti to consume large
+ amounts of CPU, causing a DoS. Thanks to Matt Schwager (@mschwager) for the
+ disclosure and to Tom Tervoort for originally publishing the category of attack.
