## codepipeline
For more info about codepipeline check:

### `iam:PassRole`, `codepipeline:CreatePipeline`, `codebuild:CreateProject, codepipeline:StartPipelineExecution`
When creating a code pipeline you can indicate a **codepipeline IAM Role to run**, therefore you could compromise them.
Apart from the previous permissions you would need **access to the place where the code is stored** (S3, ECR, github, bitbucket...)
I tested this doing the process in the web page, the permissions indicated previously are the not List/Get ones needed to create a codepipeline, but for creating it in the web you will also need: `codebuild:ListCuratedEnvironmentImages, codebuild:ListProjects, codebuild:ListRepositories, codecommit:ListRepositories, events:PutTargets, codepipeline:ListPipelines, events:PutRule, codepipeline:ListActionTypes, cloudtrail:`
During the **creation of the build project** you can indicate a **command to run** (rev shell?) and to run the build phase as **privileged user**, that's the configuration the attacker needs to compromise:

### ?`codebuild:UpdateProject, codepipeline:UpdatePipeline, codepipeline:StartPipelineExecution`
It might be possible to modify the role used and the command executed on a codepipeline with the previous permissions.
### `codepipeline:pollforjobs`
[AWS mentions](https://docs.aws.amazon.com/codepipeline/latest/APIReference/API_PollForJobs.html):
> When this API is called, CodePipeline **returns temporary credentials for the S3 bucket** used to store artifacts for the pipeline, if the action requires access to that S3 bucket for input or output artifacts. This API also **returns any secret values defined for the action**.
