The Portable SDK for UPnP Devices is an SDK for development of UPnP device and control point applications. The server part of pupnp (libupnp) appears to be vulnerable to DNS rebinding attacks because it does not check the value of the `Host` header. This can be mitigated by using DNS revolvers which block DNS-rebinding attacks. The vulnerability is fixed in version 1.14.6 and later.

Discord Recon Server is a bot that allows one to do one's reconnaissance process from one's Discord. A vulnerability in Discord Recon Server prior to 0.0.3 could be exploited to read internal files from the system and write files into the system resulting in remote code execution. This issue has been fixed in version 0.0.3. As a workaround, one may copy the code from `assets/CommandInjection.py` in the Discord Recon Server code repository and overwrite vulnerable code from one's own Discord Recon Server implementation with code that contains the patch.
