Shovel and Federation plugins perform URI obfuscation in their worker (link) state. The encryption key used to encrypt the URI was seeded with a predictable secret.
This means that in case of certain exceptions related to Shovel and Federation plugins, reasonably easily deobfuscatable data could appear in the node log.
Patched versions correctly use a cluster-wide secret for that purpose.
Patched versions:
