Immutable.js provides many Persistent Immutable data structures.

OpenTelemetry-Go is the Go implementation of OpenTelemetry.

gRPC-Go is the Go language implementation of gRPC.

etcd is a distributed key-value store for the data of a distributed system.

Handshake messages, such as KeyUpdate, are always considered as state-advancing, regardless of whether a handshake has been completed or not.

Previously, DecodeElement would reset the depth counter causing it to never fire; this could lead to stack exhaustion.

When a server is configured to support unencrypted HTTP/2, it reads a few bytes from each new connection to see if they contain the HTTP/2 client preface.

Enforce a recursion limit in Unmarshal to prevent stack exhaustion when parsing deeply-nested, recursive structures.

A norm.Iter can enter an infinite loop when handling input containing invalid UTF-8 bytes.

Previously, resolving relative paths containing parent directory ('..') segments performed string conversions and buffer rewrites on each step, resulting in quadratic time complexity and high memory allocation overhead.

Previously, pathological inputs could close an unescaped '/' early, allowing for attack-controlled data to inject arbitrary content, potentially leading to XSS.

Parsing arbitrary HTML which is then rendered using Render can result in an unexpected HTML tree.

Due to the usage of a variable time instruction in the assembly implementation of an internal function, a small number of bits of secret scalars are leaked on the ppc64le architecture.
