### Summary
All three release images ship a Brotli library that is vulnerable to
CVE-2026-111497 (out-of-bounds write in the decoder, CVSS 9.2 Critical).
New base image tags do not fix it yet:
| Image | Base | Brotli in base tag | Fixed |
| --- | --- | --- | --- |
| `devlake` | `python:3.11-slim-bookworm` (pulled in by `curl` & co.) |
`libbrotli1 1.0.9-2+b6` | `1.0.9-2+deb12u1` |
| `devlake-config-ui` | `nginxinc/nginx-unprivileged:1.31.6` / `1.31.7` |
`libbrotli1 1.1.0-2+b7` | `1.1.0-2+deb13u1` |
| `devlake-dashboard` | `grafana/grafana:13.2.4` (Alpine 3.24.2) |
`brotli-libs 1.2.0-r1` | `1.2.1-r0` |
This PR upgrades the OS packages when the image is built:
- `backend/Dockerfile`: `apt-get upgrade -y` in the `base` stage
- `config-ui/Dockerfile`: `apt-get upgrade -y`. I also switched `apt` to
`apt-get`
(stable CLI for scripts) and clean the apt lists
- `grafana/Dockerfile`: `apk upgrade --no-cache` in the existing `USER root`
step
This also picks up future Debian/Alpine security fixes on every rebuild. We
do not have to wait for upstream base images.
### Does this close any open issues?
Closes #9258
### Screenshots
N/A
### Other Information
Verified locally (`linux/arm64`, 2026-10-27):
```text
devlake (--target base) libbrotli1 1.0.9-2+deb12u1
devlake-config-ui libbrotli1 1.1.0-2+deb13u1 (htpasswd, ip
present; runs as uid 101)
devlake-dashboard brotli-libs-1.2.1-r0 (runs as uid 101)
```
Dependabot #9253 (`nginx-unprivileged` 1.31.6 → 1.31.7) touches a different
line
in `config-ui/Dockerfile`, so the two PRs do not conflict. On its own, #9253
does
not fix the CVE, because 1.31.7 still ships `libbrotli1 1.1.0-2+b7`.
The reporter asked for a new release or a re-push of `v1.0.3-beta18` with the
fixed packages. After this PR is merged, that needs a maintainer to rebuild
and publish the images.
