Managing code scanning alerts for your repository

From the security view, you can view, fix, dismiss, or delete alerts for potential vulnerabilities or errors in your project's code.

Who can use this feature

If you have write permission to a repository you can manage code scanning alerts for that repository.

Code scanning is available for organization-owned repositories in GitHub Enterprise Server. This feature requires a license for GitHub Advanced Security. Para obter mais informações, confira "Sobre o GitHub Advanced Security".

Viewing the alerts for a repository

Anyone with read permission for a repository can see code scanning annotations on pull requests. For more information, see "Triaging code scanning alerts in pull requests."

You need write permission to view a summary of all the alerts for a repository on the Security tab.

By default, the code scanning alerts page is filtered to show alerts for the default branch of the repository only.

  1. No your GitHub Enterprise Server instance, navegue até a página principal do repositório.

  2. Abaixo do nome do repositório, clique em Segurança. Guia Segurança

  3. Na barra lateral esquerda, clique em Alertas da verificação de código. Guia "Alertas da verificação de código"

  4. Optionally, use the free text search box or the drop-down menus to filter alerts. For example, you can filter by the tool that was used to identify alerts. Filter by tool

  5. Em "Code scanning", clique no alerta que você gostaria de explorar. Summary of alerts

  6. Optionally, if the alert highlights a problem with data flow, click Show paths to display the path from the data source to the sink where it's used.

    The "Show paths" link on an alert

  7. Alerts from CodeQL analysis include a description of the problem. Click Show more for guidance on how to fix your code. Details for an alert

For more information, see "About code scanning alerts."

Note: For code scanning analysis with CodeQL, you can see information about the latest run in a header at the top of the list of code scanning alerts for the repository.

For example, you can see when the last scan ran, the number of lines of code analyzed compared to the total number of lines of code in your repository, and the total number of alerts that were generated. UI banner

Filtering code scanning alerts

You can filter the alerts shown in the code scanning alerts view. This is useful if there are many alerts as you can focus on a particular type of alert. There are some predefined filters and a range of keywords that you can use to refine the list of alerts displayed.

  • To use a predefined filter, click Filters, or a filter shown in the header of the list of alerts, and choose a filter from the drop-down list. Predefined filters
  • To use a keyword, either type directly in the filters text box, or:
    1. Click in the filters text box to show a list of all available filter keywords.
    2. Click the keyword you want to use and then choose a value from the drop-down list. Keyword filters list

The benefit of using keyword filters is that only values with results are shown in the drop-down lists. This makes it easy to avoid setting filters that find no results.

If you enter multiple filters, the view will show alerts matching all these filters. For example, is:closed severity:high branch:main will only display closed high-severity alerts that are present on the main branch. The exception is filters relating to refs (ref, branch and pr): is:open branch:main branch:next will show you open alerts from both the main branch and the next branch.

Restricting results to application code only

You can use the "Only alerts in application code" filter or autofilter:true keyword and value to restrict results to alerts in application code. See "About labels for alerts not in application code" above for more information about the types of code that are not application code.

Searching code scanning alerts

You can search the list of alerts. This is useful if there is a large number of alerts in your repository, or if you don't know the exact name for an alert for example. GitHub Enterprise Server performs the free text search across:

  • The name of the alert

  • The alert details (this also includes the information hidden from view by default in the Show more collapsible section)

    The alert information used in searches

Supported searchSyntax exampleResults
Single word searchinjectionReturns all the alerts containing the word injection
Multiple word searchsql injectionReturns all the alerts containing sql or injection
Exact match search
(use double quotes)
"sql injection"Returns all the alerts containing the exact phrase sql injection
OR searchsql OR injectionReturns all the alerts containing sql or injection
AND searchsql AND injectionReturns all the alerts containing both words sql and injection

Tips:

  • The multiple word search is equivalent to an OR search.
  • The AND search will return results where the search terms are found anywhere, in any order in the alert name or details.

  5. Press return. The alert listing will contain the open code scanning alerts matching your search criteria.

Fixing an alert

Anyone with write permission for a repository can fix an alert by committing a correction to the code. If the repository has code scanning scheduled to run on pull requests, it's best to raise a pull request with your correction. This will trigger code scanning analysis of the changes and test that your fix doesn't introduce any new problems. For more information, see "Configuring code scanning" and "Triaging code scanning alerts in pull requests."

If you have write permission for a repository, you can view fixed alerts by viewing the summary of alerts and clicking Closed. For more information, see "Viewing the alerts for a repository." The "Closed" list shows fixed alerts and alerts that users have dismissed.

You can use the free text search or the filters to display a subset of alerts and then in turn mark all matching alerts as closed.

Alerts may be fixed in one branch but not in another. You can use the "Branch" filter, on the summary of alerts, to check whether an alert is fixed in a particular branch.

Filtering alerts by branch

Dismissing or deleting alerts

There are two ways of closing an alert. You can fix the problem in the code, or you can dismiss the alert. Alternatively, if you have admin permissions for the repository, you can delete alerts. Deleting alerts is useful in situations where you have set up a code scanning tool and then decided to remove it, or where you have configured CodeQL analysis with a larger set of queries than you want to continue using, and you've then removed some queries from the tool. In both cases, deleting alerts allows you to clean up your code scanning results. You can delete alerts from the summary list within the Security tab.

Dismissing an alert is a way of closing an alert that you don't think needs to be fixed. Por exemplo, um erro no código que é usado apenas para testes ou quando o esforço de corrigir o erro é maior do que o benefício potencial de melhorar o código. You can dismiss alerts from code scanning annotations in code, or from the summary list within the Security tab.

When you dismiss an alert:

  • It's dismissed in all branches.
  • The alert is removed from the number of current alerts for your project.
  • The alert is moved to the "Closed" list in the summary of alerts, from where you can reopen it, if required.
  • The reason why you closed the alert is recorded.
  • Next time code scanning runs, the same code won't generate an alert.

When you delete an alert:

  • It's deleted in all branches.
  • The alert is removed from the number of current alerts for your project.
  • It is not added to the "Closed" list in the summary of alerts.
  • If the code that generated the alert stays the same, and the same code scanning tool runs again without any configuration changes, the alert will be shown again in your analysis results.

To dismiss or delete alerts:

  1. No your GitHub Enterprise Server instance, navegue até a página principal do repositório.

  2. Abaixo do nome do repositório, clique em Segurança. Guia Segurança

  3. Na barra lateral esquerda, clique em Alertas da verificação de código. Guia "Alertas da verificação de código"

  4. If you have admin permissions for the repository, and you want to delete alerts for this code scanning tool, select some or all of the check boxes and click Delete.

    Deleting alerts

    Optionally, you can use the free text search or the filters to display a subset of alerts and then delete all matching alerts at once. For example, if you have removed a query from CodeQL analysis, you can use the "Rule" filter to list just the alerts for that query and then select and delete all of those alerts.

    Filter alerts by rule

  5. If you want to dismiss an alert, it's important to explore the alert first, so that you can choose the correct dismissal reason. Click the alert you'd like to explore. Open an alert from the summary list

  6. Review the alert, then click Dismiss and choose a reason for closing the alert. Choosing a reason for dismissing an alert É importante escolher o motivo apropriado no menu suspenso, pois isso pode afetar se uma consulta continua sendo incluída em análise futura.

    Se você ignorar um alerta de CodeQL como um falso resultado positivo, por exemplo, porque o código usa uma biblioteca de sanitização incompatível, considere contribuir para o repositório de CodeQL e melhorar a análise. Para obter mais informações sobre CodeQL, confira "Contribuir para CodeQL".

Dismissing multiple alerts at once

If a project has multiple alerts that you want to dismiss for the same reason, you can bulk dismiss them from the summary of alerts. Typically, you'll want to filter the list and then dismiss all of the matching alerts. For example, you might want to dismiss all of the current alerts in the project that have been tagged for a particular Common Weakness Enumeration (CWE) vulnerability.
