UBUNTU-CVE-2026-31842

Tinyproxy through 1.11.3 is vulnerable to HTTP request parsing desynchronization due to a case-sensitive comparison of the Transfer-Encoding header in src/reqs.c. The ischunkedtransfer function uses strcmp to compare the header value against "chunked", even though RFC 7230 specifies that...

CVE-2026-31842

Tinyproxy 1.11.3 is vulnerable to HTTP request parsing desynchronization due to a case-sensitive Transfer-Encoding check in is_chunked_transfer() (strcmp against "chunked"). RFC 7230 requires case-insensitive transfer-coding names. An unauthenticated attacker sending Transfer-Encoding: Chunked ca...

Rack's multipart parsing without Content-Length header allows unbounded chunked file uploads

Summary Rack::Multipart::Parser only wraps the request body in a BoundedIO when CONTENTLENGTH is present. When a multipart/form-data request is sent without a Content-Length header, such as with HTTP chunked transfer encoding, multipart parsing continues until end-of-stream with no total size...

CVE-2026-3945

A flaw was found in tinyproxy. An unauthenticated remote attacker can exploit an integer overflow vulnerability in the HTTP chunked transfer encoding parser. By sending a crafted HTTP request with a specially formed chunk size, the attacker can cause the proxy to miscalculate the size of incoming...
