### Impact
Token Replay Detection is an important defence in depth measure for Single Sign On solutions. In all previous 2.X versions, the Token Replay Detection is not properly implemented.
Note that version 1.0.1 is not affected. It has a correct Token Replay Implementation and is safe to use.
### Patches
The 2.5.0 version is patched.
### Workarounds
There are no workarounds with existing versions. Fixing the issue requires code updates.
