Rekor's goals are to provide an immutable tamper resistant ledger of metadata generated within a software projects supply chain.

The thread is recovered so the client receives a 500 error message and service still continues, so the availability impact of this is minimal. This has been fixed in v1.2.0 of Rekor. Users are advised to upgrade. There are no known workarounds for this vulnerability.
