Impact

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.

Patches

Patched versions:

3.10.2 3.9.18 3.8.32

Workarounds

Disable Shovel and Federation plugins.
