protobufjs: protobufjs: Denial of Service via crafted .proto schema

A flaw was found in protobufjs, a JavaScript JS library for compiling protobuf definitions. A remote attacker could exploit this vulnerability by providing a specially crafted .proto schema. This schema, designed to prematurely end an option declaration, can cause the library's parsing functions ...

USN-8650-1: Cap'n Proto vulnerabilities

Chanho Kim and Jihyeok Han discovered that Cap'n Proto incorrectly handled negative Content-Length values or excessively large chunk sizes when processing HTTP messages. An attacker could possibly use these issues to cause HTTP messages to be interpreted inconsistently, resulting in HTTP request ...

JLSEC-2026-1268 Cap'n Proto and its Rust implementation vulnerable to out-of-bounds read due to logic error handling list-of-list

The Cap'n Proto library and capnp Rust package are vulnerable to out-of-bounds read due to logic error handling list-of-list. If a message consumer expects data of type "list of pointers", and if the consumer performs certain specific actions on such data, then a message producer can cause the...

JLSEC-2026-1269

Cap'n Proto is a data interchange format and capability-based RPC system. Prior to 1.4.0, a negative Content-Length value was converted to unsigned, treating it as an impossibly large length instead. In theory, this bug could enable HTTP request/response smuggling. This vulnerability is fixed in...

JLSEC-2026-1270

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...
