Findings (7)

HIGH
Download-and-execute
L17

Detects patterns of downloading and piping to shell execution

curl -s https://raw.githubusercontent.com/babashka/babashka/master/install | bash
FIX

Download the file first, verify its integrity (checksum, signature), inspect it, then run it. Prefer package managers over raw downloads. Never fetch-and-run in one step.

FP?

Likely FP if the target is a well-known installer (e.g., rustup, Homebrew) from its canonical HTTPS domain, though the pattern is inherently risky.

HIGH
Curl or wget piped to shell
L17

Detects downloading scripts piped directly to a shell interpreter

curl -s https://raw.githubusercontent.com/babashka/babashka/master/install | bash
FIX

Download the script first, inspect it, verify its checksum, then run it. Do not pipe curl/wget output directly to sh/bash. Prefer package manager installs.

FP?

Likely FP if the download is from a well-known installer domain (e.g., brew.sh, rustup.rs), though this pattern is inherently risky even with trusted sources.

MEDIUM
Runtime URL controls agent behavior
L17

Detects skills fetching external URLs to use as runtime instructions

curl -s https://raw.githubusercontent.com + Configuration
FIX

Pin the downloaded resource to a specific version or commit hash, and verify its integrity with a checksum (SHA-256). Avoid fetching scripts or binaries from arbitrary URLs at runtime.

FP?

Likely FP if the download URL points to a well-known CDN or package registry (e.g., npmjs.com, pypi.org) and is pinned to a specific version.

LOW
Chained shell command execution
L17

Detects chained commands using shell operators with dangerous operations

curl -s https://raw.githubusercontent.com/babashka/babashka/master/install | bash
FIX

Break chained commands into discrete, individually validated steps. Avoid piping untrusted output directly into a shell interpreter.

FP?

Likely FP if the matched text is a documentation example showing a common installer one-liner for a well-known tool with a canonical URL.

LOW
Mutable GitHub raw content reference
L17

Detects references to raw.githubusercontent.com on mutable branches like main/master

raw.githubusercontent.com/babashka/babashka/master/
FIX

Replace GitHub raw.githubusercontent.com references with pinned commit SHAs instead of branch names (e.g., /commit-sha/file instead of /main/file). Branch references are mutable.

FP?

Likely FP if the raw GitHub URL points to a versioned release tag in a well-known repository, though even tags are technically mutable.

LOW
System package manager install
L23

Detects system-level package installation via brew, apt, yum, or dnf

brew install b
FIX

Pin system packages to specific versions where the package manager supports it. Document the exact packages required and prefer containerized environments to avoid system-wide changes.

FP?

Likely FP if the match is standard setup documentation listing well-known system packages (e.g., apt install git curl) that are prerequisites.

LOW
Runtime URL controlling behavior
L39

Detects URLs fetched at runtime that control or influence agent behavior without pinning

Get an API key:** Sign up at [Tabstack Console](https:// + schema
FIX

Avoid loading configuration or behavior-controlling content from runtime URLs. Bundle required configurations locally or pin remote config to versioned, integrity-verified endpoints.

FP?

Likely FP if the URL in the match is a documentation link or example URL (e.g., example.com) rather than an actual runtime-fetched configuration endpoint.
