Details

msgpackr's conversion of property names to strings can trigger infinite recursion ### 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. ### References
