REST API endpoints for code scanning
Use the REST API to retrieve and update code scanning alerts from a repository.
[D] Get a code scanning alert
Gets a single code scanning alert.
OAuth app tokens and personal access tokens (classic) need the security_events scope to use this endpoint with private or public repositories, or the public_repo scope to use this endpoint with only public repositories.
Fine-grained access tokens for "Get a code scanning alert"
This endpoint works with the following fine-grained token types:
GitHub App user access tokens
GitHub App installation access tokens
Fine-grained personal access tokens
[C] Update a code scanning alert
Updates the status of a single code scanning alert. OAuth app tokens and personal access tokens (classic) need the security_events scope to use this endpoint with private or public repositories, or the public_repo scope to use this endpoint with only public repositories.

Code scanning in GitHub Advanced Security for Azure DevOps lets you analyze the code in an Azure DevOps repository to find security vulnerabilities and coding errors.
CodeQL is the code analysis engine developed by GitHub to automate security checks. You can analyze your code using CodeQL and display the results as code scanning alerts.

Common Weakness Enumeration (CWE) is used by CodeQL to describe the vulnerabilities it detects in code scanning alerts. CodeQL's queries are designed to identify a wide range of weaknesses, and each security query is associated with one or more specific CWEs, providing developers with standardized identifiers for the types of vulnerabilities found.
By associating alerts with CWEs, CodeQL provides a structured and informative approach to vulnerability management, making it easier for development teams to understand, address, and prevent security issues.
Note: The Common Weakness Enumeration (CWE) system is an industry-standard way of cataloging insecure software development patterns. CodeQL runs hundreds of queries out of the box that are able to detect an even greater number of CWEs. We went back through our existing queries, and aligned dozens of them with updated CWE IDs to give users better insight into the potential impact of a security issue when an alert is flagged up by code scanning.
Incorrect:
[Not B]
Vulnerability Exploitability eXchange (VEX) is not used by CodeQL; rather, CodeQL and VEX are complementary tools in software security: CodeQL identifies code vulnerabilities, while VEX communicates the exploitability of a vulnerability within a specific product context, helping users focus on relevant threats.
[Not C]
GitHub Advisories (GHSA) is a database of CVEs and GitHub-originated security advisories affecting the open source world. Advisories may or may not be documented in the National Vulnerability Database. Dependency-Track integrates with GHSA by mirroring advisories via GitHub's public GraphQL API.
[Not D]
CodeQL finds the vulnerability, and CVE provides the universally recognized identifier and description for that specific vulnerability, allowing for better communication and faster response within the cybersecurity community.
Common Vulnerabilities and Exposures (CVE) is a standardized dictionary that provides unique identifiers for publicly known cybersecurity weaknesses in software and hardware. Maintained by the MITRE Corporation and funded by the U.S. Department of Homeland Security, CVE ensures a common language for cybersecurity professionals to track, discuss, and address vulnerabilities effectively across the industry. Each CVE entry includes an identifier, a description, and references to publicly available information about the vulnerability.

About enabling secure access to private registries
If your organization uses private registries, providing code scanning and Dependabot secure access to these registries will improve code analysis and allow Dependabot to update a wider range of dependencies.
About the importance of providing access to private registries
When a repository uses code stored in a private registry, some security features need access to the registry to enable them to work effectively. Without access to all the dependencies of a repository, code scanning default setup and Dependabot are limited.
Code scanning default setup access to private registries
If you do not define access to the private registries your organization uses, then code scanning will only gather necessary data from dependencies available in public registries.
Defining registry access for code scanning default setup
You need to be an organization owner to set up access to private registries in the user interface.
You can also use the REST API with organization owner or {read,write}_org_private_registries permission.
Note:
1. On the Settings tab for the organization, scroll down to the "Security" section and select Secrets and variables.
2. In the expanded list of secrets and variables, select Private registries to display the "Private Registries" page.
3. Select New private registry to add access details for a private registry.
4. Use the URL and Type fields to define the location and type of the registry:
