CVE-2026-40560 Starman versions before 0.4018 for Perl allows HTTP Request Smuggling via Improper Header Precedence

Starman versions before 0.4018 for Perl allows HTTP Request Smuggling via Improper Header Precedence. Starman incorrectly prioritizes "Content-Length" over "Transfer-Encoding: chunked" when both headers are present in an HTTP request. Per RFC 7230 3.3.3, Transfer-Encoding must take precedence. An...

Numeric Truncation Error

Overview Affected versions of this package are vulnerable to Numeric Truncation Error in the chunk size parsing process when handling HTTP requests with Transfer-Encoding set to chunked. An attacker can cause HTTP request or response smuggling by sending a chunk size value that parses to 2^64 or...

CVE-2026-32240: Numeric Truncation Error

Cap'n Proto is a data interchange format and capability-based RPC system. Prior to 1.4.0, when using Transfer-Encoding: chunked, if a chunk's size parsed to a value of 2^64 or larger, it would be truncated to a 64-bit integer. In theory, this bug could enable HTTP request/response smuggling. This...
