| Doc Text: |
A flaw was found in cpp-httplib, a C++ HTTP/HTTPS library. A remote attacker can exploit this vulnerability by sending a specially crafted compressed HTTP request. While the library checks the size of the compressed data, it does not properly limit the size of the data after decompression, leading to excessive memory consumption. This can result in a Denial of Service (DoS), making the affected system unavailable.
