📝 WalkthroughWalkthroughThree remote installation flows now download scripts to temporary files, verify SHA-256 checksums, and execute pinned versions. A recursive audit test checks app-catalog Dockerfiles and shell scripts for unverified curl or wget shell pipelines. ChangesRemote installer verification
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The installer changes improve integrity checking, but the audit can miss unsafe remote-script pipelines and code-server is not actually installed at the declared version. These gaps should be corrected before merge to avoid false security assurance and nondeterministic images. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

In `@app-catalog/streaming/code-server/Dockerfile`:
- Line 27: Update the code-server installation command invoking
/tmp/code-server-install.sh to pass the CODE_SERVER_VERSION value via the
installer’s --version argument, preserving the intended 4.96.0 pin.
In `@tests/scripts/test_audit_s2_22.py`:
- Line 75: Update the file filter in the audit test so
framework-integration.yaml files are included in the scan, while preserving the
existing Dockerfile and shell-script handling. Ensure the audit covers files
such as framework-integration.yaml instead of excluding them through the current
condition.
- Line 36: Update the audit logic around _has_sha256_check so checksum
validation is associated with the specific download-and-execute pipeline rather
than any sha256sum -c anywhere in the file. Reject direct remote curl | sh or
wget | bash pipelines, and require validation of the downloaded file before it
is executed.
- Around line 13-14: Update UNSAFE_CURL_PATTERN and UNSAFE_WGET_PATTERN to match
shell pipelines using optionless, short-option, or long-option curl/wget
invocations, including forms such as curl URL and wget -qO- URL, followed by a
pipe to sh or bash. Preserve URL matching while allowing the common option and
argument variations.

🌐 Web query:
site:coder.com/docs/code-server/install code-server install.sh --version
💡 Result:
The code-server install script does not support a --version flag to display the version of the installed script or the code-server software [1]. Instead, the --version flag in the install script context is used as an input argument to specify a particular version of code-server to install [1]. You can use the flag as follows: curl -fsSL https://code-server.dev/install.sh | sh -s -- --version=X.X.X If you wish to check the version of code-server that is currently installed on your system, you should run the command: code-server --version For help with the installation script and to see other available flags, you can run the script with the --help flag [1]: curl -fsSL https://code-server.dev/install.sh | sh -s -- --help
Citations:
Pass CODE_SERVER_VERSION to the installer.
The installer uses the latest release when no version argument is provided. The image can therefore install a release different from 4.96.0. Pass --version="${CODE_SERVER_VERSION}" to pin the installation.

Match all curl and wget shell pipelines.
These patterns miss valid commands such as curl URL | sh, long-option forms, and common wget -qO- URL | sh pipelines. Match optionless, short-option, and long-option forms before sh or bash.

Bind checksum validation to the specific download.
_has_sha256_check(content) scans the whole file. An unrelated sha256sum -c can therefore allow a later curl | sh or wget | bash pipeline. Reject direct remote pipelines and require checksum validation for the downloaded file before execution.

Audit framework integration YAML files.
Include framework-integration.yaml files in the scan. The current filter excludes app-catalog/agents/deer-flow/framework-integration.yaml, which contains curl -LsSf https://astral.sh/uv/install.sh | sh.
