- Summary
- msgpackr's conversion of property names to strings can trigger infinite recursion
- Details
-
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.
