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...

AZL-79800 CVE-2026-32240 affecting package capnproto 1.0.1-4

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...
