    1.10.1· Vendor fix available
    Issue
    Impact When decoding user supplied MessagePack messages, users can trigger stuck threads by crafting messages that keep the decoder stuck in a loop. Patches The fix is available in v1.10.1 Workarounds Exploits seem to require structured cloning, replacing the 0x70 extension with your own (that throws an error or does something other than recursive referencing) should mitigate the issue.

    Recommended action: Upgrade to 1.10.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
