The change looks small. Access and data behaviour change.

A code or package update can alter authentication, validation or data handling across a customer flow.

The release still runs the wrong user gains access

Security-sensitive regressions can pass functional checks and still change who can see or change data.

Code review asks

Does the change work?

Release owners need

Which access or data flows changed?

A package update changes authentication behaviour

A new default accepts a token that the previous version rejected.

A package update changing authentication defaults and exposing the wrong account data
Package changed access behaviour changed
A release owner connecting a source change to changed access decisions and affected customer data flows
Source change found access impact unclear

The evidence gap appears at release

Release owners need to connect the source change to every access and data flow it affected.

When it matters

Where small changes cross security boundaries

01

Authorization defaults

A new version changes which roles can complete a workflow.

02

Validation behaviour

An input check starts accepting or rejecting different data.

03

Data handling

A change exposes, stores or transforms customer data differently.

04

Audit evidence

Release owners cannot link the source change to affected controls and workflows.
