| # This is a GitHub workflow defining a set of jobs with a set of steps. | |

| # This workflow use aquasecurity/trivy to scan the images we have published for | |
| # known vulnerabilities. If there are such that can be patched, we let this | |
| # workflow fail to signal that unless we make an exception, which we do for the | |

| # About environment: watch-dependencies | |

| title: Vulnerability patch in ${{ matrix.image_ref }} | |
| labels: image:rebuild-to-patch-vuln | |
| body: | | |
| A rebuild of `${{ steps.image.outputs.name }}` has been found to influence the detected vulnerabilities! This PR will trigger a rebuild because it has updated a comment in the Dockerfile. | |
| ## About | |
| This scan for known vulnerabilities has been made by [aquasecurity/trivy](https://github.com/aquasecurity/trivy). Trivy was configured to filter the vulnerabilities with the following settings: | |
| - ignore-unfixed: `true` | |
| ## Before | |
| Before trying to rebuild the image, the following vulnerabilities was detected in `${{ steps.image.outputs.spec }}`. | |
| ${{ steps.analyze.outputs.md_summary_1 }} | |
| ## After | |
| ${{ steps.analyze.outputs.md_summary_2 }} | |
| commit-message: | | |
| Patch known vulnerability in ${{ matrix.image_ref }} |
