This is usually bad practice because manual construction could accidentally result in a SQL injection. An attacker could use a SQL injection to steal or modify contents of the database. Instead, use a parameterized query which is available by default in most database engines.

However, certain container images may contain `setuid` or `setgid` binaries that could allow an attacker to perform privilege escalation and gain access to sensitive resources.

An attacker could use this vulnerability to execute arbitrary commands on the host, which allows them to download malware, scan sensitive data, or run any command they wish on the server. Do not let users choose the command to run. In general, prefer to use Python API versions of system commands. If you must use subprocess, use a dictionary to allowlist a set of commands. - metadata: - category: security - confidence: HIGH - cwe: - - 'CWE-78: Improper Neutralization of Special Elements used in an OS Command (''OS Command Injection'')' - cwe2021-top25: true - cwe2022-top25: true - impact: MEDIUM - likelihood: HIGH - owasp: - - A01:2017 - Injection - - A03:2021 - Injection - references: - - https://semgrep.dev/docs/cheat-sheets/python-command-injection/ - subcategory: - - vuln - technology: - - flask - mode: taint - options: - symbolic_propagation: true - pattern-sanitizers: - - patterns: - - pattern: $DICT[$KEY] - - focus-metavariable: $KEY - pattern-sinks: - - patterns: - - pattern-either: - - patterns: - - pattern: subprocess.$FUNC(...) - - pattern-not: subprocess.$FUNC("...", ...) - - pattern-not: subprocess.$FUNC(["...", ...], ...) - - pattern-not-inside: | - $CMD = ["...", ...] - ... - subprocess.$FUNC($CMD, ...) - - patterns: - - pattern: subprocess.$FUNC(["$SHELL", "-c", ...], ...) - - metavariable-regex: - metavariable: $SHELL - regex: ^(sh|bash|ksh|csh|tcsh|zsh)$ - - patterns: - - pattern: subprocess.$FUNC(["$INTERPRETER", ...], ...) - - metavariable-regex: - metavariable: $INTERPRETER - regex: ^(python|python\d)$ - pattern-sources: - - pattern-either: - - patterns: - - pattern-either: - - pattern: flask.request.form.get(...) - - pattern: flask.request.form[...] - - pattern: flask.request.args.get(...) - - pattern: flask.request.args[...] - - pattern: flask.request.values.get(...) - - pattern: flask.request.values[...] - - pattern: flask.request.cookies.get(...) - - pattern: flask.request.cookies[...] - - pattern: flask.request.stream - - pattern: flask.request.headers.get(...) - - pattern: flask.request.headers[...] - - pattern: flask.request.data - - pattern: flask.request.full_path - - pattern: flask.request.url - - pattern: flask.request.json - - pattern: flask.request.get_json() - - pattern: flask.request.view_args.get(...) - - pattern: flask.request.view_args[...] - - patterns: - - pattern-inside: | - @$APP.route($ROUTE, ...) - def $FUNC(..., $ROUTEVAR, ...): - ... - - focus-metavariable: $ROUTEVAR - severity: ERROR - - id: python.flask.security.injection.tainted-sql-string.tainted-sql-string - languages: - - python - message: Detected user input used to manually construct a SQL string.

When using `workflow_run`, the Action runs in the context of the target repository, which includes access to all repository secrets. Normally, this is safe because the Action only runs code from the target repository, not the incoming PR. However, by checking out the incoming PR code, you're now using the incoming code for the rest of the action. You may be inadvertently executing arbitrary code from the incoming PR with access to repository secrets, which would let an attacker steal repository secrets. This normally happens by running build scripts (e.g., `npm build` and `make`) or dependency installation scripts (e.g., `python setup.py install`). Audit your workflow file to make sure no code from the incoming PR is executed.

However, certain container images may contain `setuid` or `setgid` binaries that could allow an attacker to perform privilege escalation and gain access to sensitive resources. To mitigate this risk, it's recommended to add a `securityContext` to the container in the pod, with the parameter `allowPrivilegeEscalation` set to `false`. This will prevent the container from running any privileged processes and limit the impact of any potential attacks.
