cpp-httplib: cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library
CVE-2026-28435 is fixed in cpp-httplib on 1 platform by DEBIAN-CVE-2026-28435 (version 0.41.0+ds-3), released March 4, 2026. It is not reported as exploited. Patch Radar priority: High.
cpp-httplib is a C++11 single-file header-only cross platform HTTP/HTTPS library. Prior to 0.35.0, cpp-httplib (httplib.h) does not enforce Server::set_payload_max_length() on the decompressed request body when using HandlerWithContentReader (streaming ContentReader) with Content-Encoding: gzip (or other supported encodings). A small compressed payload can expand beyond the configured payload limit and be processed by the application, enabling a payload size limit bypass and potential denial of service (CPU/memory exhaustion). This vulnerability is fixed in 0.35.0.
