Ordered by severity, then signals introduced in this release. Hidden characters are shown as ⟨U+…⟩.
-
`execv` called with a non-literal path (ast pass, confidence 0.90)
execv(ptr, (const char * const *)(newargs));
return fail("Could not exec %s", ptr);
}
likely benign
LLM, confidence 0.60
A C launcher calls execv on a runtime-resolved binary path to start the GUI application.
Reasoning
execv with a runtime-computed path is a common launcher pattern (exec the real GUI binary after setup). The snippet alone does not show where ptr comes from, so malicious use cannot be excluded, but the surrounding code reads as a legitimate launcher that replaces itself with the target binary.
-
`os.popen` called on a non-literal command — runtime-determined shell invocation (ast pass, confidence 0.85)
out = os.popen(q_cmd)
try:
binary_rpms = []
dismissed
LLM, confidence 0.90
Runs an rpm query command via os.popen while building RPM packages.
Reasoning
os.popen on a constructed rpm query command is standard distutils code that queries rpm for output file names. Legitimate build tooling, not obfuscation.
-
`subprocess.getoutput` called with a literal shell command (ast pass, confidence 0.70)
vendor_hook = subprocess.getoutput('rpm --eval %{__os_install_post}')
dismissed
LLM, confidence 0.95
Fetches the RPM __os_install_post macro value with a literal shell command.
Reasoning
A fixed literal rpm --eval command via subprocess.getoutput is ordinary build-time introspection in the RPM builder.
-
`eval` called on a non-literal expression (ast pass, confidence 0.70)
expected = '"static", "shared", "dylib", "xcode_stub"'
if lib_type not in eval(expected):
raise ValueError(f"'lib_type' must be {expected}")
fmt = getattr(self, lib_type + "_lib_format")
likely benign
LLM, confidence 0.90
Evaluates a hardcoded string literal of library type names to validate lib_type.
Reasoning
eval on a fixed local string of quoted format names is a known idiom in distutils; the input is not attacker-controlled in this snippet.
-
`exec` called on a non-literal expression (ast pass, confidence 0.70)
code = f.read().replace(r'\r\n', r'\n')
exec(code, g) finally:
sys.argv = save_argv
likely benign
LLM, confidence 0.90
Executes the project's setup.py script inside run_setup.
Reasoning
Executing the setup script via exec is the documented purpose of distutils run_setup; the comment acknowledges it. Expected behavior for a build tool.
-
`__import__` called on a non-literal expression (ast pass, confidence 0.70)
try:
__import__(module_name)
module = sys.modules[module_name]
except ImportError:
likely benign
LLM, confidence 0.85
Dynamically imports a named distutils command module.
Reasoning
Dynamic __import__ of a command or module name during option handling is standard distutils plugin loading, guarded by ImportError handling.
-
identifier `Dεbug` mixes scripts: Latin + Greek (in string/comment) (raw pass, confidence 0.40)
caplog.set_level(logging.DEBUG)
log.debug('Dεbug\tMėssãge')
log.fatal('Fαtal\tÈrrōr')
assert caplog.messages == ['Dεbug\tMėssãge', 'Fαtal\tÈrrōr']
-
identifier `Fαtal` contains homoglyph candidates: α (03B1)→a (in string/comment) (raw pass, confidence 0.35)
log.debug('Dεbug\tMėssãge')
log.fatal('Fαtal\tÈrrōr')
assert caplog.messages == ['Dεbug\tMėssãge', 'Fαtal\tÈrrōr']
-
identifier `Fαtal` mixes scripts: Latin + Greek (in string/comment) (raw pass, confidence 0.40)
log.debug('Dεbug\tMėssãge')
log.fatal('Fαtal\tÈrrōr')
assert caplog.messages == ['Dεbug\tMėssãge', 'Fαtal\tÈrrōr']
-
identifier `Dεbug` mixes scripts: Latin + Greek (in string/comment) (raw pass, confidence 0.40)
log.fatal('Fαtal\tÈrrōr')
assert caplog.messages == ['Dεbug\tMėssãge', 'Fαtal\tÈrrōr']
-
identifier `Fαtal` contains homoglyph candidates: α (03B1)→a (in string/comment) (raw pass, confidence 0.35)
log.fatal('Fαtal\tÈrrōr')
assert caplog.messages == ['Dεbug\tMėssãge', 'Fαtal\tÈrrōr']
-
identifier `Fαtal` mixes scripts: Latin + Greek (in string/comment) (raw pass, confidence 0.40)
log.fatal('Fαtal\tÈrrōr')
assert caplog.messages == ['Dεbug\tMėssãge', 'Fαtal\tÈrrōr']
-
`compile` called on a non-literal expression (ast pass, confidence 0.70)
log.info("byte-compiling %s to %s", file, cfile_base)
compile(file, cfile, dfile)
else:
log.debug("skipping byte-compilation of %s to %s", file, cfile_base)
dismissed
LLM, confidence 0.90
Byte-compiles a Python source file during installation.
Reasoning
compile of a source file to bytecode during install is ordinary byte-compilation logic in distutils util.
-
file imports decoder module(s) zlib, bz2, lzma, gzip and calls `.decompress()` — embedded payload decompressed at runtime (ast pass, confidence 0.75)
dismissed
LLM, confidence 0.80
Creates a zlib decompressor for streaming reads of compressed tar archives.
Reasoning
decompressobj is used for streaming tar decompression of the archive being read, which is the purpose of the tarfile module, not a hidden embedded payload.
-
`eval` called on a non-literal expression (ast pass, confidence 0.70)
try:
return eval(use)
except TypeError:
return replace
likely benign
LLM, confidence 0.75
Evaluates a caller-supplied expression in a vendored functools helper.
Reasoning
eval of a 'use' expression in a retry/replace helper is a vendored utility pattern; the input is developer-supplied, not external. Mild concern only.
-
`compile` called on a non-literal expression (ast pass, confidence 0.70)
try:
compile(python_expression, "", "eval")
except SyntaxError:
message = f"Invalid license expression: {raw_license_expression!r}"
dismissed
LLM, confidence 0.90
Compiles a license expression to check its syntax without running it.
Reasoning
compile with mode eval is used purely to validate a license expression syntax and is not executed.
-
`exec` called on a non-literal expression (ast pass, confidence 0.70)
try:
exec(code, locals()) except SystemExit as e:
if e.code:
likely benign
LLM, confidence 0.85
Executes setup.py during the PEP 517 build backend run.
Reasoning
build_meta executes the project's setup script in a controlled namespace as part of the PEP 517 build hook. Intentional and documented.
-
`marshal.load` deserializes Python bytecode from bytes — code-object sink (ast pass, confidence 0.75)
f.read(skip)
code = marshal.load(f)
f.close()
safe = True
likely benign
LLM, confidence 0.80
Loads compiled module bytecode to scan it for safe-import checks.
Reasoning
marshal.load reads bytecode from a file during egg byte-code analysis (checking for symbol references). Standard for this module, though marshal is a sensitive deserializer.
-
`inspect.getouterframes` — call-stack frame introspection (ast pass, confidence 0.70)
frames = inspect.getouterframes(run_frame)
for frame in frames[2:4]:
(caller,) = frame[:1]
dismissed
LLM, confidence 0.90
Inspects the call stack to find the frame that invoked the install command.
Reasoning
getouterframes is used to locate the caller of run_setup for install-time behavior. Benign introspection.

`marshal.load` deserializes Python bytecode from bytes — code-object sink (ast pass, confidence 0.75)
f.read(8) code = marshal.load(f)
elif kind == PY_FROZEN:
code = _imp.get_frozen_object(module, paths)
likely benign
LLM, confidence 0.80
Reads a module's bytecode to extract symbol constants for dependency checks.
Reasoning
marshal.load of a module's compiled code is the standard way depends.py extracts constants from installed modules; reading local bytecode files, not fetched payloads.
-
file imports decoder module(s) marshal and calls `exec`/`eval`/`compile` — multi-stage payload shape (ast pass, confidence 0.80)
elif kind == PY_SOURCE:
code = compile(f.read(), path, 'exec')
else:
likely benign
LLM, confidence 0.90
Compiles source read from a module file in setuptools' dependency-inspection code.
Reasoning
The compile call reads a module's source file from disk to inspect or load it, which is standard behavior for a module-introspection utility. The marshal import and compile together reflect ordinary bytecode and source handling, not a hidden payload stage.
-
`compile` called on a non-literal expression (ast pass, confidence 0.70)
elif kind == PY_SOURCE:
code = compile(f.read(), path, 'exec')
else:
likely benign
LLM, confidence 0.90
Same compile of a module file's source, flagged separately as non-literal compile.
Reasoning
This is the same compile call as the previous finding, flagged again by the dynamic-execution signal. It compiles source from a module file that the library itself located, so the non-literal argument is expected.
-
`__import__` called on a non-literal expression (ast pass, confidence 0.70)
__import__(cython_impl, fromlist=['build_ext']).build_ext except Exception: return False
likely benign
LLM, confidence 0.85
Dynamic import used as an optional Cython availability check inside a try block.
Reasoning
The import of cython_impl is wrapped in a broad try/except that returns False on failure. It checks whether Cython is available, which is a common feature-detection pattern. The critical severity comes from the dynamic-import signal, not from anything malicious in the snippet.
-
`compile` called on a non-literal expression (ast pass, confidence 0.70)
norm_script = script.replace('\\r\\n', '\\n')
code = compile(norm_script, script_name, 'exec')
exec(code, namespace)
likely benign
LLM, confidence 0.90
Compiles a setup script's text in the launcher, as intended.
Reasoning
This is setuptools' script launcher, which runs a setup script inside a namespace by design. Compiling the script's text is the documented purpose of the module, and the comment marks the exec as intentional.
-
`exec` called on a non-literal expression (ast pass, confidence 0.70)
code = compile(norm_script, script_name, 'exec')
exec(code, namespace)
likely benign
LLM, confidence 0.90
Executes the setup script in the launcher's namespace, by design.
Reasoning
This exec runs the compiled setup script in the launcher's namespace. That is the module's stated function, and the code is not obfuscated or fetched from elsewhere.

`__import__` called on a non-literal expression (ast pass, confidence 0.70)
return importlib.__import__(name, *args, **kwargs)
with suppress(KeyError):
likely benign
LLM, confidence 0.90
Test wrapper around importlib.__import__ used to intercept imports.
Reasoning
This is a test helper that wraps importlib.__import__ to observe or patch imports. Test code of this kind is routine and has no network or obfuscation indicators.
-
`exec` called on a non-literal expression (ast pass, confidence 0.70)
loc = {}
exec(finder, loc, loc) loc["install"]()
likely benign
LLM, confidence 0.90
Test executes the generated editable-finder code in a local namespace.
Reasoning
This test executes a generated editable-install finder in an isolated namespace and then calls install. The exec is the thing under test, and the comment marks it as intentional.
-
`eval` called on a non-literal expression (ast pass, confidence 0.70)
raw_req,
(req for req in reqs if for_extra(req) and eval(req, extra=extra)),
)
)
likely benign
LLM, confidence 0.70
Evaluates requirement markers to filter requirements for an extra in wheel metadata.
Reasoning
The builtin eval does not accept an extra keyword, so this call is probably a local helper or marker evaluator named eval that the snippet does not show. It filters requirements by extra markers, which is ordinary metadata handling. The snippet is short, so some doubt remains.
Run disclude locally to verify. Add --format sarif for SARIF output. Add --llm (with an API key in the environment) to include the LLM review.
