Impact

A malformed proposed entry of the intoto/v0.0.2 type can cause a panic on a thread within the Rekor process. The thread is recovered so the client receives a 500 error message and service still continues, so the availability impact of this is minimal.

Patches

This is fixed in v1.2.0 of Rekor.

Workarounds

No
