When a CVE is reported we are bound to patch the existing OCI artifacts if within the EOL maintenance window

based on when the artifact was published there are 2 different methods to operate

In this case OCI tags include the patch version of the application To be able to fix the OCI image with the related tag we need to:

• checkout a new branch from the tag and name it cve/<tag>

git switch --detach v1.19.0
git switch -c cve/v1.19.0

• apply oci-factory workflow patch
• apply CVE patches (conventional commits won't trigger a release here, so using a chore/feat/fix won't make a difference)
• retag to the head fo the branch and push the tag

git tag -f v1.19.0
git push -f --tags origin v1.19.0

• let the machinery do its job

In this case OCI tags don't include the patch version anymore, we should be able to simply use the current workflows

Two cases are possible now:

If tag is the latest, making fix commits to patch the issue and then use the release-please flow as usual That will trigger the usual release PR with a patch version change, OCI tag won't be affected and OCI cli will push the <major>.<minor> with the following

    - source: canonical/identity-platform-login-ui
      commit: c80436a8d26abd33f2d1901ac59393fde69dd987
      directory: ./
      release:
        1.21-22.04:
            end-of-life: "2024-11-26T00:00:00Z"
            risks:
                - candidate
                - edge

In the case tag is not on the same minor the same process describe for pre #353 merge applies with some exceptions,

To be able to fix the OCI image with the related tag we need to:

• checkout a new branch from the tag and name it cve/<tag>

git switch --detach v1.19.0
git switch -c cve/v1.19.0

• apply git patch below (to be changed soon) to avoid pushing to latest stable
