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.
Package changed access behaviour changed
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.
