+
+Create this issue under https://dev.gitlab.org/gitlab/gitlabhq
+
+Set the title to: `Description of the original issue`
+-->
+
+### Prior to starting the security release work
+
+- [ ] Read the [security process for developers] if you are not familiar with it.
+- [ ] Link to the original issue adding it to the [links section](#links)
+- [ ] Run `scripts/security-harness` in the CE, EE, and/or Omnibus to prevent pushing to any remote besides `dev.gitlab.org`
+- [ ] Create a new branch prefixing it with `security-`
+- [ ] Create a MR targeting `dev.gitlab.org` `master`
+- [ ] Add a link to this issue in the original security issue on `gitlab.com`.
+
+#### Backports
+
+- [ ] Once the MR is ready to be merged, create MRs targetting the last 3 releases, plus the current RC if between the 7th and 22nd of the month.
+    - [ ] At this point, it might be easy to squash the commits from the MR into one
+    - You can use the script `bin/secpick` instead of the following steps, to help you cherry-picking. See the [secpick documentation]
+    - [ ] Create each MR targetting the stable branch `X-Y-stable`, using the "Security Release" merge request template.
+    - Every merge request will have its own set of TODOs, so make sure to
+      complete those.
+- [ ] Make sure all MRs have a link in the [links section](#links)
+
+[secpick documentation]: https://gitlab.com/gitlab-org/release/docs/blob/master/general/security/developer.md#secpick-script
+
+#### Documentation and final details
+
+- [ ] Check the topic on #security to see when the next release is going to happen and add a link to the [links section](#links)
+- [ ] Find out the versions affected (the Git history of the files affected may help you with this) and add them to the [details section](#details)
+- [ ] Fill in any upgrade notes that users may need to take into account in the [details section](#details)
+- [ ] Add Yes/No and further details if needed to the migration and settings columns in the [details section](#details)
+- [ ] Add the nickname of the external user who found the issue (and/or HackerOne profile) to the Thanks row in the [details section](#details)
+- [ ] Once your `master` MR is merged, comment on the original security issue with a link to that MR indicating the issue is fixed.

+
+<!-- This issue outlines testing activities related to a particular issue or epic.
+
+[Here is an example test plan](https://gitlab.com/gitlab-org/gitlab-ce/issues/50353)
+
+This and other comments should be removed as you write the plan -->
+
+## Introduction
+
+<!-- Briefly outline what is being tested
+
+Mention the issue(s) this test plan is related to -->
+
+## Scope
+
+<!-- State any limits on aspects of the feature being tested
+Outline the types of data to be included
+Outline the types of tests to be performed (functional, security, performance,
+database, automated, etc) -->
+
+## ACC Matrix
+
+<!-- Use the matrix below as a template to identify the Attributes, Components, and
+Capabilities relevant to the scope of this test plan. Add or remove Attributes
+and Components as required and list Capabilities in the next section
+
+Attributes (columns) are adverbs or adjectives that describe (at a high level)
+the qualities testing is meant to ensure Components have.
+
+Components (rows) are nouns that define major parts of the product being tested.
+
+Capabilities link Attributes and Components. They are what your product needs to
+do to make sure a Component fulfills an Attribute

+## Capabilities
+
+<!-- Use the ACC matrix above to help you identify Capabilities at each relevant
+intersection of Components and Attributes.
+
+Some features might be simple enough that they only involve one Component, while
+more complex features could involve multiple or even all.
+
+Example (from https://gitlab.com/gitlab-org/gitlab-ce/issues/50353):
+* Repository is
+  * Intuitive
+    * It's easy to select the desired file template
+    * It doesn't require unnecessary actions to save the change
+    * It's easy to undo the change after selecting a template
+  * Responsive
+    * The list of templates can be restricted to allow a user to find a specific template among many
+    * Once a template is selected the file content updates quickly and smoothly
+-->
+
+## Test Plan
+
+<!-- If the scope is small enough you may not need to write a list of tests to
+perform. It might be enough to use the Capabilities to guide your testing.
+
+If the feature is more complex, especially if it involves multiple Components,
+briefly outline a set of tests here. When identifying tests to perform be sure
+to consider risk. Note inherent/known levels of risk so that testing can focus
+on high risk areas first.
+
+New end-to-end and integration tests (Selenium and API) should be added to the
+[Test Coverage sheet](https://docs.google.com/spreadsheets/d/1RlLfXGboJmNVIPP9jgFV5sXIACGfdcFq1tKd7xnlb74/)
+
+Please note if automated tests already exist.
+
+When adding new automated tests, please keep [testing levels](https://docs.gitlab.com/ce/development/testing_guide/testing_levels.html)
+in mind.

+- [ ] Make sure to add [`redirect_from`](https://docs.gitlab.com/ce/development/writing_documentation.html#redirections-for-pages-with-disqus-comments)

+<!--
+Describe in detail what your merge request does, why it does that, etc. Merge
+requests without an adequate description will not be reviewed until one is
+added.
+
+Please also keep this description up-to-date with any discussion that takes

+
+Make sure to remove this comment when you are done.
+-->
+
+Add a description of your merge request here.
+
+## Database checklist
+
+- [ ] Conforms to the [database guides](https://docs.gitlab.com/ee/development/README.html#databases-guides)
+
+When adding migrations:
+
+- [ ] Updated `db/schema.rb`
+- [ ] Added a `down` method so the migration can be reverted
+- [ ] Added the output of the migration(s) to the MR body
+- [ ] Added tests for the migration in `spec/migrations` if necessary (e.g. when migrating data)
+
+When adding or modifying queries to improve performance:
+
+- [ ] Included data that shows the performance improvement, preferably in the form of a benchmark
+- [ ] Included the output of `EXPLAIN (ANALYZE, BUFFERS)` of the relevant queries
+
+When adding foreign keys to existing tables:
+
+- [ ] Included a migration to remove orphaned rows in the source table before adding the foreign key
+- [ ] Removed any instances of `dependent: ...` that may no longer be necessary
+
+When adding tables:
+
+- [ ] Ordered columns based on the [Ordering Table Columns](https://docs.gitlab.com/ee/development/ordering_table_columns.html#ordering-table-columns) guidelines
+- [ ] Added foreign keys to any columns pointing to data in other tables
+- [ ] Added indexes for fields that are used in statements such as WHERE, ORDER BY, GROUP BY, and JOINs
+
+When removing columns, tables, indexes or other structures:
+
+- [ ] Removed these in a post-deployment migration
+- [ ] Made sure the application no longer uses (or ignores) these structures
+
+## General checklist
+
+- [ ] [Changelog entry](https://docs.gitlab.com/ee/development/changelog.html) added, if necessary
+- [ ] [Documentation created/updated](https://docs.gitlab.com/ee/development/documentation/index.html#contributing-to-docs)
+- [ ] [Tests added for this feature/bug](https://docs.gitlab.com/ee/development/testing_guide/index.html)
+- [ ] Conforms to the [code review guidelines](https://docs.gitlab.com/ee/development/code_review.html)
