GitHub Actions is a CI/CD platform allowing users to automate their build, test and deployment pipeline. But do not know how i must type it. Available to private repositories only, you can configure these policy settings for organizations or repositories. Kudos to GitHub for fixing this security flaw. For example, an application deployment can be triggered after a developer pushes a new version of the code to a repository. The service principal ID and key match the ones in the Azure portal. Each personal access token has one or multiple scopes such as8: An interesting scope is workflow, because it grants the ability to add and update GitHub Actions workflow files (we will detail the concept of workflow right after). For more information about the GITHUB_TOKEN, see "Automatic token authentication." Turns out for whatever reason you have to use ssh and cannot use PAT and https.

When you create (Personal access tokens) select under Permissions -> Repository ->permissions Its not an organization member, but counts as PR approval, and effectively allows the attacker to approve their own PR, basically bypassing the branch protection rules with the result of pushing code to a protected branch without any other organization members approval. Creating these protection rules that require one approval on a pull request by another organization member significantly reduces the risk of compromising an account, as the code needs to be manually reviewed by another user. Sign in Contrary to secret variables in variable groups, there is no need to obfuscate the output of the script execution, since Azure Pipelines do not seem to detect secure files extraction. Also, do you confirm you are the owner or a contributor to this repo?
